He is right.
I have also problem with my old packageNames. They dont show ads.
–In my case; I applied for admob but the post with the PIN code is never arrived. Then admob finished to send ads. I think that is the reason. They don’t send ads to the apps with the package names, which adMob already limited or blocked.
According to a koder we have to change the packageName and upload to play store as a new app.
It means, losing all existing users and reviews. And starting from beginnig.
i put ads manager ads in my app then i update my app on google play now i received ads fraud policy issue on my app please tell me any one also facing this issue ?
