For some reason, my P3P simply climbs to infinity when i activate the RTH function. I've tried setting to 200, 250, 300 max altitude. At one point it went to 600' and still climbing. I took control of left stick climb to stop climbing and it then returned home from that altitude safely. It's never done this before. The only thing I've changed is I've disabled the MAX distance option so I can fly much further. I'm updating firmware because the DJI App says firmware update required. Not sure if that will affect it as I've had it work properly last week when it also said update required...any suggestions or experience with this?
