With the Mavic Mini1 and the DJI Fly software and a Samsung S21 phone, can I return to a previous version of software. 2 days ago an update was loaded into my device and now I have no picture on the screen. If I hit record I can play back the recording and everything is fine. Also if I use Dronelink I have a picture on the phone screen. So it has to be the software. I spent 3 hours and 5 different people from DJI and no one would listen. They just want me to return the drone.
