I plugged my P4 into the Assistant and it said I had an update, something to do with the picture quality so I decided to update. I went through the recalibration process and test flight the drone seems to be stuck in "Sports Mode". I switched between "P" and "S" but this made no difference. Other than that I had a section of screen on the iPad that was segmented. I landed the drone, shut down and restarted everything but nothing changed. I am about to do a factory reset, I hope I haven't opened a can of worms! Anyone else?
