Interstitial iAd call only works once

Question

I have a spritekit game, the ad is pre-loaded every time I start the game using [UIViewController prepareInterstitialAds];And after the game it should show the ad with [self.view.window.rootViewController requestInterstitialAdPresentation];, and it works fine, but only for the first time. An ad is shown only once. After a failure in another game, the ad does not appear, although it is preloaded. Any suggestions?

Answer 1

Is it installed where it runs

[self.view.window.rootViewController requestInterstitialAdPresentation]; 

every time the game ends?
