I’m having an issue with App Open Ads in my Android Kotlin application. The ad loads successfully but doesn’t show immediately on the first launch of the app. However, if I exit the app and reopen it, the ad displays without any problems.

I’m integrating App Open Ads using AdMob in my Android app. The ads load and display correctly when the app is opened from the background or after the first launch, but on the very first launch, I get a CORS error and the ad fails to load.
