React Native FB App install deep link issue - ios

Question

My FB Deferred deep link is: einee://free_marilyn_monroe=true.
Clicking on Install in the test ad (when the app is already installed) works fine.
However, when the app is not yet installed and clicking on the FB ad Install button which takes the user to the App Store, the deep link is not found when the app launches.
This is my code in React Native to detect the deep link:
Linking.getInitialURL().then((url) => {
if(url){
if(url.includes('free_marilyn_monroe=true')){
// Deep link detected code
}
}
// ...
This is my AppDelegate.m code:

- (BOOL)application:(UIApplication *)application continueUserActivity:(NSUserActivity *)userActivity restorationHandler:(void (^)(NSArray *restorableObjects))restorationHandler {
return [RNBranch continueUserActivity:userActivity];
}

Am I detecting the deep link wrong? Please help!

Answer 1

You have used url scheme for deep linking, suggest to use universal linking to handle the case when the app is not installed. Checkout the difference between two here.
