Maybe someone here can help. Did the latest update and was going to calibrate the compass since I have read so much about the issues that others are having. I haven't flown this in two months since I jumped on the DJI buss. So what's happening is once everything is powered p and connected I go into the calibrate menu and try to start the compass calibration. Ive done this many times since may when I first got the TH. When I hit the button I get a warning that GPS was lost and it does nothing after that. It gets stuck on acquiring and unless I shut down and restart it stays that way? any Ideas ?? Thanks
