I just unpacked and tried the new mavic air. I updated the RC and MA. I tried to calibrate the gimbal and the screen stays at 10% forever and the gimbal did not move at all at start. Is it broken? Anybody else with the same issue??   

Have you removed the gimbal clamp?

It moved down and up at the start, Sorry. Yes the cap is off.
But then I can't calibrate it.

Hi there, the firmware update is successful, right? Could you post a screenshot of About page and a short issue video for better assistance? Thanks in advance!
