HI GUYS,
Can anyone help me please,
I can't get passed the phone number verification page on the app. i put my UK mobile number in.. and its telling me its invalid.. i therefore cannot get rid of this screen to get to the main go fly screen.. i can see it underneath , ready to go but if i hit back button all i get is the verification screen again.. W T actual F???  I can't attach a screen shot as they are too big apparently.... i now have a new spark and cannot use it because i don't have a chinese mobile number.... crazy... it didn't happen with my other one..

Re-install the APP.I had the same problem.
And went to DJI's store and completed my personal information.
Home address!!!!

re-start phone and re-install app.

Reinstall the APP, then power on the aircraft when GPS signal is good and then connect it with the controller to check whether the linking phone number pops up.
