4.19 and 4.20 does not load databases, or loads for a very long time,
It also doesn’t work with your drone.
Android 11/12 were highly frustrating considering DJI. I found that the apk from DJI works fine on android 11/12/13 while that from the playstore did not worked. Atleast in my region (India) the app has been removed from the playstore. and downloaded apk from DJI works without any hiccup.
