Hey @JLH1964, I tried making the "test app" like you said, and yea, it did work... I saw an AD!!! Now, I just don't get it though... if it works on the test app, why doesn't it work in my actual game (I followed the exact same Admob setup process with both apps)? So, why aren't any ads showing up in my game (not even banner ads will show up on start of layout, I put in both banner and interstitial ads)?
In my test app, I only put one line of code, and it worked: when"myadButtton" is touched --> preload interstitial
--> show interstitial
