Anyone know how to transfer ownership of a P3 w/DJI? I have two P3Ps and am selling one tomorrow. I've tried doing a factory reset from (DJI GO), logging out of DJI GO, formatting the SD card (from DJI GO). I was hoping it would prompt me to activate/register it again like it did when it was new. Only thing I have left to try is to login to DJI from (DJI GO) with a new userid. And as some have suggested on previous posts, I don't see anywhere that my two P3Ps are identified separately (DJI GO - iOS).
