I inserted a banner ad (admob) into my game on Android Studio, and when I testing it on my phone (loading the apk file into the phone) works correctly. The problem is that when I reopen the game the next day (and not updating and redownloading it again) the advertising disappears and it doesn’t load. The same thing also applies to the interstitial ad that I inserted (both in the mainActivity). Is this a problem that solves itself when I load the game on the play store and i connect it with my admob account, or it’s the code? Can someone help me? Thank you!

Here is the code:

“MAINACTIVITY”
mainActivity banner ad

“XML mainActivity”
xml banner ad

The ad has to be always in the game. I tried setting the visibility of the banner on “VISIBLE” but it doesnt change anything.
