when opening the dji app a telefonnumber „mainland china“ is necessary. the app is blocking any further step. no possibilty flying the drone.
i am in europe, no chinese telefonnumber! ?

I'm sure I got that after using the simulator.
I think I needed to factory reset the PLUS controller. Maybe just reinstall the app on other controllers.
Anyway, factory reset of controller was done using Assistant 2.
Its a known bug and has been seen before though I'm not exactly sure what triggers it. Maybe not being connected to internet?

Hopefully someone else can come up with something a bit more concrete than my waffle.

like  everybody said link phone number to china on deplay so can`t fly.......got back home, powered up controler but not drone,i could now get in settings.and found the general setting.. under maps..it was enable amap (for china mainland) i disable that.... and under that again... calibrate map coordinates (for china mainland) was enabled..again i disable that.. when outside with drone and was able to fly.. hope this helps some of you guys

I have a same problem with my P4P+ after using the simulator.

Yes. The reset to factory settings helps to fix it.

Hello Sualk, I'm sincerely sorry for the inconvenience. Reset to factory settings will figure it out. Alternatively, you can take it to the outdoor with good GPS signal and contact the local internet to see whether it helps.
