Its been a while since I've flown my P3P. I updated all the FW yesterday and took it out to fly and got the distance height restriction. I always put my device in airplane mode before I fly so a call won't interrupt my flight. Do I have to leave the device connected to the Internet the entire time I'm flying now so I won't get this restriction?
I have had this issue in the past, and all I did was land the craft after confirming that I was not in beginner mode i went back flying and all was well.
If this helps, I use a non-internet enable table when flying (I do however before I leave home, always log out of the DJI Go application, then back in). I have never had an issue with distance when not flying in beginners mode.
