Need help with Admob Please!

So I've had my game on the play store for a week now and only test ads are getting displayed. I think there's something in the coding. I removed the * in testing devices. Can someone please fix my issue? I want REAL ads to appear, not test ads.


This is the MFA of one of my frames where I display ads.

This is my app on the store

I also have this written in the coding, Set Admob Test Devices to GetDeviceIdAdMob$( "AdMob" ) Is that the issue?
