This chick does awesome fix vids.
Replacing that bracket that’s snapped off isn’t hard mate, take the top of the Mavic off and there are two screws holding it there. Undo them and screw in new one that you buy prior to repairs.
You’ll be ok!
It’s happened to myself yesterday too guys, bloody sport mode strikes again haha small crash and the gimble popped up.
Just a heads up too, make sure you go into gimble settings and auto align it for peice of mind that it’s correct too
