sounds like the op has many same issue as i did,i was around too many electronics,moved to the next room and problem solved.I'm not sure this sounds correct. The controller connects to the Mavic, you plug in the phone and the app does not auto launch? Okay, I could see that. But then you restart the phone? Why restart the phone instead of simply starting up the app manually? Okay, so you restart the phone and and then all of a sudden something displays "version check"? What displays "version check"? Something briefly connects? What connects? The app? If the app, so it did launch for some reason?
