My N1 controller went in for service, and then came back... now all good. I tried to bind the N1 controller to the Mini 3 Pro that  it was bound to before service, now it says  "aircraft bound to another account , change and try again (-53268)"
There is only one account....  I bought the mini 3 pro direct from DJI...

Hello, there. Sorry for your inconvenience. May we have the serial number of your Mini 3 Pro and your DJI account for further confirmation? You can send the information via PM. At the same time, please try to log out and log in to the DJI Fly app and check again. Please keep us updated.
