I used to use p4p + iPad mini 2 (No sim,iphone tetherling)
But iPad mini 2 was not strong enough so just decided to buy new iPad 9.7inch 128G celllar.
And just tried to fly my p4p but MAP never comes up....
Actually when open the app, Map is shown exactly where I am.
But after take off,Map goes grey out and never shown.
Is that DJI GO4 app's problem?or iPad's problem?
Anyone in same situation? Please help me.
Thanks in advance.

App's firmware is the newest version. Go back to use iphone or iPad mini4, it works well

Please enter the FPV page, then switch to the map view, lock the compass, as you can see the pic below, then back to the homepage of the APP, then reenter the FPV page. See if it works.
