Many thanks, @appyet. I see that the new release includes new features. Please, consider to include an option to select which languages I want to include in an AppYet app APK. I think it's a very important feature. Related to the AdMob problem, I think I have some clue as to why some of us do not work properly. I installed it correctly to the applications that I created a few years ago, but in the older ones it does not work for me. Maybe the old ones use some other system different from the new ones or that some old function that was removed is giving problems?
