I was flying in France when this came out ( I am normally UK based), absentmindedly updated on my iPhone and then flew my Mavic Pro. Had all sorts of weird gimbal activity and some slightly unusual flight behaviour. It did settle down about 20 seconds or so into the flight but was a little disconcerting. I have since rolled back to the earlier version using advice from this site on using iTools4 which I must say seems to have worked a treat.
Note to self "Pay attention to which apps are getting updated next time, dummy"
