I have stated elsewhere (Here) that I am struggling with the “CPU Overload” error on my iPad Mini 4 using the FLY app. This morning it was just abysmal. The screen kept freezing up and I thought I was in real danger of loosing the drone at one point (only RTH saved me). I clearly have ALOT of learning to do with this new drone. Have never experienced anything like this with the GO4 app on the same tablet with my M2Z.
One other thing I am considering is whether the temperature was adding to this. It was about 3 Degrees and the iPad Mini 4 has previously had a history with not liking the cold much. It doesn’t account for the CPU error, but may account for the screen freezing.
