I have been using my dedicated Ipad mini with my P3P for 2 years without a problem. I updated the AC to 1.11.20. RC to 1.9.2 and Go App to 3.1.13, all without a problem. First time I flew, I get a message "Mobil device fully loaded" and a partial green screen in the camera view. I tried another Ipad Mini. Same problem. I tried my Iphone 7plus, and had no problem. Looking at the forums, it seems i'm not the only person. Any word on DJI fixing this problem? At this point, I really don't want to, and should not have to, upgrade my device. Most of what I have read points to the Go App.
