Mavic Air 2. Has been fine for the past month. However, I noticed yesterday that the compass pointed generally the opposite of the way that the aircraft was pointed. Then I also realized that it was showing the aircraft behind me when it was in front of me. I've calibrated the compass and the IMU. After powering down and moving to a different area, it worked correctly again. Then today went to the same area that worked last night and it was backwards again. Wondering if anyone may know why this is happening? Thanks in advance.
