I have had this issue from day one. The image on the screen appears to start yawing on it own and sometimes will not stop. If I push the yaw centering button, camera returns to center. Latest firmware installed, Dji has replace my ship and now the gimbal... Tried multiple IMU, COMPASS and Gimbal Calibrations, cold and room temp. Still exhibits this behavior. Any suggestions as to what I am doing wrong? LEaving the country in two weeks for a really important gig.

Is the yaw movement happening with multiple lens's? I have the same issue with the Olympus 45mm but not with my 12 or 7.5.

Yes all lenses, including the 12mm, it is jus that due ot the angle of view it can be more or less emphasized. IMPOSSIBLE to Timpelapse/Hyperlapse, as well as flying in truly at straight line...without compensating yaw. Dissapointing….
