I have been flying the Mavic for over 9 months and it has been fantastic. After seeing the great reviews, I recently purchased the DJI Goggles. Unfortunately, I am not able to get the "Head Tracking Gimbal" function to work. The goggles connect to the Mavic as expected and all other functions work well (Liveview, playback, etc.) When I select the "Head Tracking Gimbal" option in the menu, the Mavic camera does not move with the head movements. While I have not yet been able to test this outside due to the cold weather, it is my understanding after viewing videos online that the function should still work indoors. I have contacted DJI support on two occasions and the only suggestions I received was to insure the correct versions and try using Fixed Wing mode. I have updated and refreshed the Mavic and Goggles to the latest version (10.4.0100) using DJI Assistant 2 with no change. On a side note, the "Reset Motion Control" menu option is not selectable. Could this be an indicator of a configuration issue? Any suggestions before returning the goggles as defective?
