Unable to load rewarded video ads sometimes - ios

Question

I've launched an iOS app, but I am having problems loading rewarded video ads using the Google Mobile Ads SDK.
When a player clicks the button to see a video ad, the player is shown a video very few times. Most of the time, the user is shown an error of Admob being unable to fill the request:
Error Domain=com.google.ads Code=1 "Request Error: No ad to show."
Sometimes it will take them several clicks before getting one, and sometimes they just can't get one no matter how many clicks. This issue happens more with my rewarded videos, but it also happens with my banner ad. Sometimes Google is unable to provide me with a banner ad. Does anyone know why this is not working?
My code for ads:
override func viewDidLoad() {
super.viewDidLoad()
if let view = self.view as! SKView? {
// Load the SKScene from 'GameScene.sks'
let scene = MainMenu(view.bounds.size, self, nil)
scene.scaleMode = .aspectFill
// Present the scene
view.presentScene(scene)
view.ignoresSiblingOrder = true
view.showsFPS = false
view.showsNodeCount = false
view.showsPhysics = false
GADRewardBasedVideoAd.sharedInstance().delegate = self
GADRewardBasedVideoAd.sharedInstance().load(getRequest(),
withAdUnitID: rewardAdId)
// In this case, we instantiate the banner with desired ad size.
if GameViewController.bannerView == nil {
GameViewController.bannerView = GADBannerView(adSize: kGADAdSizeBanner)
GameViewController.bannerView.adUnitID = bannerId
GameViewController.bannerView.rootViewController = self
GameViewController.bannerView.load(getRequest())
GameViewController.bannerView.isHidden = true
addBannerViewToView(GameViewController.bannerView)
}
authenticateLocalPlayer()
QuestManager().checkForRefresh()
}
}
public func getRequest() -> GADRequest {
let request = GADRequest()
return request
}
public func displayRewardedVideo() {
if GADRewardBasedVideoAd.sharedInstance().isReady {
GADRewardBasedVideoAd.sharedInstance().present(fromRootViewController: self)
} else {
GameViewController.loadVideo()
}
}
public static func loadVideo(){
if !GADRewardBasedVideoAd.sharedInstance().isReady {
GADRewardBasedVideoAd.sharedInstance().load(GADRequest(),
withAdUnitID: rewardAdId)
}
}
func rewardBasedVideoAdDidClose(_ rewardBasedVideoAd: GADRewardBasedVideoAd) {
GADRewardBasedVideoAd.sharedInstance().load(getRequest(),
withAdUnitID: rewardAdId)
if let scene = gameScene {
scene.audioManager.unmmute()
}
print("Video did close")
}

Answer 1

I am currently working at a certain company that provides tons of free mobile applications with Admob as a freelancer, so I'm quite adept with it.
Anyways, what I've learned from the manager of my company (they also have a Google Admob consultant there), is that the ad to be shown in an app can be dependent to the country that the user is in. For instance, I'm here in South East Asia and they're in Europe. I experience some times when I do not receive a banner ad, but in their place, they always receive all types of ads.
As long as your project is complying the the Google Admob's rules (e.g. do not display interstitial ad after the other one at a short gap of time), and you receive some ad at least once every while, then I believe you're doing fine.
I hope this helps.
