Indeed AVIC is slow on Android 11 (I just updated from LineageOS 17.1 to 18.1). Takes at least twice as long to startup and really is slow displaying the map.
All other apps are fine, including Igo-LUNA.
Can this be fixed somehow?
... It must have sth. to do with the new external files handling (permissions) of Android 11 ... so this app seems to be too old now ...
