Hey. I check admob advertising in the application for android. In Google created 2 advertisements - banner and interstitial. Exported apk, as debag. I call configuration settings through events and it shows that everything is ok. But when I start creating banner and interstitial advertising, I get "failed to load". In the console, writes "Rejection from 'advert' handler".
The question is, to test advertising in the apk, i need a signed apk or is it something else? Maybe time should pass after creating an admob account?
