Can't really help, but for clarity, what ANEs are you using to display Admob ads? I'm putting out 2 versions of my app, one paid and the other with ads. I'm using distriqt/ANE-Adverts and still working on the ad supported version. Test interstitials are working, but I'm concerned with putting the app out and ads not showing up, at that point you just gave the app away.
" my All Android live Apps in playstore are working and this issues happens when i take new apk for update game.."
What differences are there between the other apps and this one? Different runtimes, ane, etc?
