We have been developing Android applications for our company for more than 5 years. Recently we are getting support calls from our users that they can no longer install our apps on Galaxy S10 after the Android 11 updates. On a vanilla Android 11 there is no issue nor there was any issue on the same S10 running Android 10. No other brand seem to have an issue (but most are not yet on Android 11). What could be the cause?
