Just had a similar issue using my iPad
mini 4 flying the
air 2s. Had previously turned off the photo cache, as others said it would help. Still had warnings on the iPad about insufficient storage or memory and could effect performance. Just the other day soon after I took off screen keep freezing and drone was not responding the drone was not far away but it was mid-afternoon and I couldn't see it ever once in awhile I could hear it. I kept trying to get the drone back to me, but unable to. Hit return to home and started praying screen Still coming in out of being froze, could not see or hear the drone, and not sure what was happening hit return to home this time I believe I used the symbol on the IPad and not the button on the controller. In a little while I heard say it was landing Still did not see it or hear it. The screen unfreeze long enough for me see it land in some grass. I had taken off at a baseball field, but within 50 yards there were trees and a creek, a pasture with chest high grass. At this point I thought I had lost my drone never to be seen again. Trying to remember how to get to the find my drone got it going but It seemed to be difficult to tell where the drone showed up on the map and I was in relationship to it. Walked several ways and it didn't seem to show me getting closer or farther away. Started to look in another place and could finally see I was getting closer. It had landed about 25 yards to the north of the take off point. It should have been easy for me to see it land but I was looking over head. Needless to say I was glad I had not given up on finding my drone witch took about 30 minutes. I will no longer be using the iPad
mini 4 to fly the
air 2s. Found a good used iPad 6th generation that I will be using from now on.
