I have a P3P and P3A. I had the same thing happen to my P3P. But first my problem was a pixelating issue on screen with my P3P. After trying a few suggestions, I sent it in for repair. Nothing wrong with that. I was told that I needed to replace my prop motors. Cost was more than the value. Then I noticed it would not go any higher than 100 ft after I got it back. Usually they automatically upgrade any software unless they are told not to. I was thinking that was the issue. Then my P3A started doing the same thing, maxing at around 100 ft. After more research, I sent that one to a different repair shop (certified). Found nothing. Another $250 total. After getting it back and missing out on flying time, I was thinking about the fact that it might have been the ipad that I used because it never went to the repair places. I decided to try using my phone instead of the ipad and guess what happened? It worked. It didn't stop at 100 ft for both quads and had no pixelation on the screen with the P3P. I deleted the app on the ipad. Put a new DJI Go app back on it and they work great ! It's a shame that this wasn't suggested from either repair places. It only cost approx. $500. I guess it could have been worse......
