I published an culture news app on Google Play Store, developed in Android Studio about a year ago. Few days ago I integrated firebase ads in this app the way this guy done it in this video https://www.youtube.com/watch?v=eRT1Ho39MLU&t=5s
I published this update with ads included, but when I downloaded it from play store and start it, ad banner is there but all that shows is "nice job! you're displaying a 320x50 test ad from AdMob.
When I'll actually get real ads? Should I do something more?
