I purchased a Air 2s just before Christmas 2021 and then an Ipad Air 4th Gen to use with my controller. It was working fine and now all of the sudden when I connect the Ipad Air 4 to my controller and turn on the controller and drone, the DJI fly app says my drone isn't connected. I then turned everything off and connected my Iphone 13pro and it connected fine. Any ideas? It's a bummer if I can't use the iPad.
