Only the "world " map showing on the Go4 app, first time of use, new Mavic 2 perhaps they will appear after compass calibration …help
Tried reinstalling the DJI Go 4 app?
If you are indoors without a GPS fix on the M2, that’s all you see.
Take it in the garden and get a GPS fix on your M2 and it should locate you correctly and load the detailed map.
Thanks will do
