I have noticed that the people that cannot install my app all have Android 12 (since there are no installations with Android 12 in the statistics)
Has anyone else experienced this issue? Is there something extra you need to add?
Lastly, the APK has been installed on Android 12 in testing, but unable to install it from Google Play
Following this migration guide helped
