What about the announcement ”Aircraft Disconnected”? I flew yesterday my Mavic Pro and during the flight that text appeared white on red on the screen. At start it said “the HP has updated”. The flying went fine, the sticks were ok. The picture on screen OK but no satellite info at top of the screen. Button C1 didn’t work. I unconnected and reconnected the cable between RC and iPad Mini4 and the white “In Flight (GPS)” on green appeared again but no satellite info. The manual says nothing about it.

  

I also have that message on DJI GO 4 app. App is not connecting with controller and aircraft, Phantom 4 Pro, both of which are powered up and linked to each other.
