Changing phones on mavic 2 pro

[Ninabeertje]

Me and my wife are flying the mavic 2 pro. I connected my phone to the controller and did fly several times. My wife wants to use her own phone because i am not always there. If i connect her phone the app says controller needs to be updating but i am sure it is up to date and updated with my phone. It seems i need to bind again to the drone. Why i do not know because controller is already connected to the drone.
The question is: can you use two different phones to fly or is the phone first connected to the controller not exchangable.

You can use two different phones. I use a Samsung tablet for Go 4 and an iPad for Litchi. You should be able to ignore the update notice.
