It's under Gimbal Settings in the Starlink app: https://support.autelrobotics.com/s...derstanding-the-starlink-app-interface#gimbal My app doesn't quite look the same when in Gimbal settings. I don't have Calibrate as an option.
Definitely not on FPV, that mode tilts with the drone. Mine is always tilted even when the drone is hovering.
In my Manual beginning on page 50, under "Settings" section it talks about all the stuff you can change. On page 54 it addresses "Gimball Roll". Maybe your answer is there??
