If its an IOS device its limited to whatever version is on the app store, unlike Android phones you cant choose what version, as a sidenote i have an old mini 4 on IOS12 and the latest version just crashes out when launched but on my iphone 13 with ios 18 it works fine
Well I don't have a smart phone but I do have an apple tablet, I think it is a 6th generation. I read that you need a 8th generation or newer for dji go.
