We built a slack app, got it approved in the marketplace, etc. Now we want to add more functionality which will require us to add a scope. The question is - what will happen to the existing app installations? Will the app stop working for them once the new scope is approved? We couldn't find any description of how this is supposed to behave.
Existing installations will continue to work as they always had and won't be disrupted by the changes you make to your app. They also won't have the new scopes unless the app is re-installed. If your app has the ability to DM users who have installed your app already, if might be good to DM those users and prompt them to re-install so they get the full experience of your app.

I am building out a iOS & Android app. My app may not fully scale to support users and have some limited functionality out the gates. I wanted to put an invite list on the front of registration like Mailbox did a few years ago.
I was trying to read the Apple app store guidelines to creating a "waiting list / invite list" and couldn't get a clear picture. I assume Android is more flexible on this, so I figured I could start with Apple's guidelines first.
Here is what I can find.
In Apple's docs, it says under 3.2.2 "UnAcceptable"
(v) Arbitrarily restricting who may use the app, such as by location or carrier.
In this specific case, I am not blocking by location or carrier. I am just putting up a wall to use the app since some of my users can use it in a limited form, but I can't open it up to everyone on Day 1.
I understand I can run a "testflight" release, but I wanted to make our app available in the App Store for anyone to download since it will be publicly available, just not fully ready for a million people to hit it. My understanding is that the testflight release requires a bit more work based on their docs and isn't as simple as just putting it in the public app store so anyone can get to it.
Apple has the ultimate authority for approving and rejecting apps in their app store so nothing on SO can really be perfect advice. If you are really concerned about approval, you can try to contact apple developers support. Here are a few things I would advise:
Make sure in the developer notes for Apple when you submit to them you include a free account.
In the notes for the app store let the users know that it may take up to __ hours for their registration to get activated.
My understanding is you are doing this to handle the volume of users as you are launching the app. Be advised though that if you start restricting users too much you will possibly get poor reviews. Only restrict usage if absolutely required. If you run into issues make sure you are communicating with the users so they understand.
Good luck with you new app!
I have developed a game, in order for the game to work all users need to be on the same version of the game.
Apple have complained about this and said:
Your app includes an update button or alerts the user to update the app. To avoid user confusion, app version updates must utilize the iOS built-in update mechanism.
The problem with relying on this is that it makes updating purely optional, and I am worried that if I remove this a lot of users will end up complaining that the app doesn't work and leave bad reviews.
I have seen many games where they forcefully update.
Is there a work around for this?
You can force a user to have a certain minimum version. I do it in my apps, and many other apps do it, including Clash of Clans.
Just remove the update button. You should redirect them to your app in the app store when you alert them that there is an update.
For example, your app makes a call to your server, which includes the current version. Your server responds with a message that the user must update. Your app shows the message, and when they dismiss the alert, the app redirects them to your app in the app store.
Maybe these get approved because Apple never gets to see it work like that, but certainly, they must know that Clash of Clans does it.
I want to decrease a few options I have given out as free in one of my app (Universal iOS app) but I do not want any current users to update and lose those options.
Is there any way I can update my app without offering it to the current users. Only new users get the new app?
No it's not possible.
Update is always available for all users that purchased the app.
You may think about adding in-app for those feature and make those in-app already available for the application already installed. The problem is that if the user deleted the application from the phone and install it again, you have no way to know he purchased a previous version (except if you have user login inside the application).
In iOS, is there a way to figure out the version of app the user originally bought from?
For example, what if i want to implement some special behavior only for user who purchased v1.0. one obvious "feature" is disable in-app purchase so they can enjoy the rest without paying? I thought up some ways to do it but unfortunately, it wont survive the test if the user deleted the app and also i didnt user icloud early enough to persist this metadata.
Unfortunately this can't be done. At least not in any perfect manner. There is no API to get any details about the user and their purchase. If your 1.0 version of the app doesn't already persist some meaningful clue, your only solutions would be partial at best.
Your issue is made worse if you already have newer versions of the app out (such as 1.1) and you want to add this new feature to a newer version (1.2 or 2.0). There is no way to know if anyone ever had 1.0.
You basically have two options:
Leave it alone. You can't convert a paid app to a free-with-IAP app without hurting at least some portion of your existing customers. If anything, leave the app paid but add IAP for any new functionality. This way, everyone pays the same for the base app and everyone has the option to pay more, through IAP, for additional features.
Depending on your ethics and the number of existing customers, you could just make the switch and make existing customers pay again for functionality they already paid for. Obviously, this is a bad idea but it is an option.
I have an app in the iTunes store that has full functionality. I attempted to release a Free version which contains half of the functionality, and contains a link to the full version if the user tries to use the other functions.
Apple rejected the app on the basis that rather than having two apps, I ought to have the main app released for free and have the extra functions unlockable using in-app purchasing.
That's fine; I can do this. The only problem is that since I released the full version initially, some people have already paid for and downloaded the full version. When I update this app so that it is free, it will be restricted by default. Those users that have paid for the full version will have lost the functionality they've paid for.
I don't really want to release a second version of the app since I intend on continuing to update the app and managing two release streams would be unwieldy.
Is it possible to somehow offer for free the in-app purchase to those users that have already bought the full version of my app when I update the app to the new (free, in-app supported) version?
Edit: An (unpreferred) alternative would be a way of refunding the purchases to the original buyers, along with a note explaining why. Any ideas how?
What I'd do is add a already paid option within the application itself, and then allow users to enter a license code, or email address depending what you prefer, Which you can automatically issue from their contact details if you have them or ask them to contact you if you don't, which most will as they have paid.
Now as far as the licensing and the verification of these codes you could setup a cheap VPS which verify s the code and only activates with codes that you have entered on the server, meaning you won't fall victim of Keygeners.
Just my 2 cents.
If your app doesn't currently have a username/password registration, I would suggest releasing an update to the paid app that explains to your users on an initial popup view something like:
Thank you for supporting our app. Due to changes in Apple's policies, we will be converting this app into a free app with in-app upgrades. Since you already purchased the full app, you will be awarded all features! Please input an [email_address or username] so that we can provide a painless transition.
If your app has a user login mechanism already in place (username/password), then just store those details and have the user log in later in the "free" app to unlock all of the features.
Obviously, both of these suggestions require a backend for validation, but shouldn't be too difficult to create that.
This is tricky due to section 3.3.3 of the license agreement and Attachment 2. I'm not a lawyer so I'll save my interpretation but, read them.
Another option would be to make the free version a new, different app and leave the original one in the store but unavailable. Then you can still publish updates to it but new users won't see it. Apple would probably allow this considering you are still only presenting one app to new users. The downsides are (1) you have to maintain two versions and (2) you have to start over in terms of reviews etc.
