Rewarded ads are working in debug mode, but not in release mode

What happened?

In release mode the rewarded ads are not showing at all..i Read that minifyEnabled=true could be the issue but this was not the case. Even with false it's not working. I cannot find any solution on this..Interestial ads play well in release mode.

Platforms

Android, but have not tested behavior on iOS
