Gimbal movement has stopped working completely. 1 Week old mavic mini. A few minor bumps but nothing that should cause that. Flies perfectly (hovered a bit indoors and stopped due to gimbal) Gimbal is very free and not obstructed. all wires and ribbons look fine.

There's nothing we can do. Try calibrating the gimbal and see if it responds to that.
