Read the message on-screen carefully, as I recall it says to calibrate the compass or move the aircraft. The calibrate bit is erroneous, the correct action is to move the aircraft. The issue is the surface the aircraft is on when you switch it on. If that surface contains a ferrous metal, it will affect the compass reading during initialisation.
Or it is a completely Bogus warning having nothing to do with Compass needing to be calibrated or there being any source of magnetic interference.
When I first got my Mavic Pro P, GO-4 app would pop up a message about Compass on virtually every first flight of day, intermittently with subsequent flights for day.
At first, calibrating compass was S.O.P. for flying Mavic Pro P. Moving drone to another location made no difference, still get message about compass. Even saw few cases where drone took off from a location without getting message, but on next flight from same exact spot, I would get Compass message.
Later on, after wasting a lot of time with compass calibrations, I got to where I would do one compass calibrate for day of flying; then completely ignore any subsquent messages.
The Bogus compass warnings stopped after I switched from using iOS version of GO-4 on iPad or iPhone; to using Android version of GO-4 on DJI's CrystalSky Ultra bright.
