I am using a Matrice 200 with an iPAd Mini. I have always used the DJI Ground Station Pro app for all my missions, and now when I try ot fly it gives me an error telling me that I need to calibrate the compass, but I cannot figure out how. I looked in the manual and it says it can be done in the DJI Go 4 app, but I downloaded it and it says that it is no longer compatiable with this drone. Tried other apps like DJI Fly and DJI Pilot, but still no luck. Does anyone know how to cabilrate the compass and get rid of this error?

Hi, there. Sorry to hear about the issue you've encountered. Could you please give us a screenshot of the error message? Thank you.
