I have a p4p and have been flying it with my ipad air 2 without any problems. A new iOS came out for my ipad 11.0.2 when I downloaded it I was having problems. I wiped my ipad clean and had to download my apps over again. When I download the go 4 app and it tells me to sign in and I did it doesn’t know I’m flying a p4p it says spark and a picture of a spark is on the screen. I tap enter device and it says not connected. Also when I look at settings like return to home it is set at 0 and max alt is at 0 also. First I need to be able to connect to the drone and is there somehow to set the settings to the factory settings? I’m really lost and would appreciate any help. Thanks
