When I first got the DJI goggles everything was fine. Then I run the update on the Mavic.  Gimbal head tracking stopped working. I put the goggles onto asstsnant 2 and ran that up date. Head tracking ran again but when I rotate yaw left or right, the gimbal jumps, jitters. All other functions are fine on the gimbal.
Any ideas?

More information is required. What versions on what devices were you at before and after updating?
