I have a Mavic Pro that is about 2 years old.  It has never been crashed/dropped.  I am having problems with getting the compass to calibrate.  The remote/DJI Go 4 app screen shows "? Calibrate Error" (see pic).  I have reset/calibrated the IMU with success, I have calibrated the compass multiple times with success, I have changed locations, and the error message will not go away.  Any help with this would be great.  Thanks

Hi. thank you for reaching out and we do apologize for the inconvenience. Can you please try to sync all your flight records in DJI GO 4 app then try to uninstall and reinstall the app to see if the error will disappear. Please keep us posted for us to help you further. Thank you for your kind and understanding. Cheers!

I have backed up the flight data, deleted and re-installed the app, and calibrated the compass.  It still shows that the compass needs calibration and has the error. It goes into GPS mode and the controller goes green, but the error is still present. Also, the rear lights link red and yellow.

I moved locations this morning and still have the same problem.  It flew fine until it disconnected imaging.   It wasn't far away so I was able to land without problems.  It never lost GPS on the remote.  I checked to see if the compasses were normal in the advanced settings and compass 1 was green with no problems and compass 2 was disconnected (while in flight).  I checked it against my other mavic pro and both compasses worked while in flight.  Any help would be great.

Thank you for the additional information and we're sorry to know that you still experience the issue. I just want to clarify if your Mavic Pro's arms are folded when receiving that error? If yes, the reason for this is the motors are very close to the compass. The permanent magnet in the motor may interfere with the compass. When you calibrate the compass, the arms need to be unfolded. Please keep us posted. Thank you for your kind and understanding. Cheers!
