Hi everyone... I Flew, created and then favourited a bunch of waypoints to be repeated every couple of months but I did a firmware update and they got wiped. I redid all the waypoints again and, as before, saved them all as my favourites. They were all there at the end of the day. A month later I went to fly them and they are gone again!!! Does anyone know why this might be? Also does anyone know where on the tablet (android) the waypoints are saved so I can move them straight away and store them next time as this is getting frustrating and expensive in reshoots!? I asked DJI and they weren't very helpful apart from to say 'They're probably in the DJI Go folder'

Any help much appreciated...

Realistically, your solution is to go with a 3rd party app.

DJI's autonomous nav functions are just not fit for purpose - they delivered the bare minimum to satisfy some promises made mid last year about groundstation support.
Using waypoints in DJI GO is not a workable solution, as you are experiencing.

Pity.
