Has anyone else experienced the Automatic Gimbal Calibration stopping at 83%, abruptly closing and then the display pops up with a message saying "Gimbal Calibrated"? It Doesn't really inspire confidence that the calibration was actually completed.

See screengrabs below:

Anyone get to 100% Calibration?

Mine  never gets to 100% only 83%, then it flicks back to main app screen and says gimbal is 100% calibrated

Does the gimbal tilt after calibration? Please try to calibrate IMU first then calibrate the gimbal. And please make sure that all firmware is up to date.
