I went to fly my p3p for the second time after updating my iphone 6 to ios9. The app was not showing that the aircraft was connected but it had camera feed and then looking at the about in the app I see that it shows my rc at 1.3.2 app 2.20 and aircraft Unknown?
is this b/c I removed the Bin file from the sd?
I had problems after updating to IOS 9 so I went back to IOS 8.4.1. It probably depends on which Apple device you update. For me it was my IPad Mini 2. The DJI GO APP is not 100% compatible with IOS 9.
