For some reason google admob package for unity is problematic. In a way that it breaks in release. The answer to this is not rocket science but a change in the Configuration in the publisher settings. Tick all, you’ll get need it later.

IF you have debug it properly, You will have noticed checking release in minify causes the problem. while in debug all is good. It is because in release, everything is minified. And this causes issues. The Google admob package breaks when that happens. That is why you need to check the custom proguard file. Search for that file in the location in the image. and add this lines.

-keep class com.google.android.gms.ads.** { *; }
-keep class com.google.android.gms.ads.AdRequest { *; }
-keep class com.google.android.gms.ads.AdListener { *; }

This will prevent minification of the admob files and your code will not break.
