iPad losing gps
I replaced an old iPad Air 2 (cellular) with a new iPad Air 3 (cellular) in June 2020, only to find the new iPad losing gps speed and heading frequently, reading zero knots and no heading on the Navionics boating app and the Garmin Pilot app. Restarts, Restores, reinstalling iOS and apps all failed to improve the performance. iPhone 7 running same apps in same locations never failed, always showing heading and speed. I understand that iPad Pro models are having same problems. I am awaiting a new replacement iPad Air 3 to see if that will perform correctly. This seems to be a hardware gps problem. Any other suggestions?
iPad Air, iPadOS 14
