On the latest firmware update, (where you update controller and drone for waypoints), I was able to up the
MP2 via DJIgo4 app, but when I tried to update the controller (app was telling me on the main screen that controller needed up dating), I keep getting a message that "firmware updated failed, retry", even though I had seen a 100% complete message on the drone.
Went to Mac, plugged drone into assistant 2 for Mavic, and it showed drone was current. So I then updated controller with Assistant 2 for Mavic, restarted DJI404 and it showed both controller and drone current.
