just want to add...after updating everything, app, RC and Mavic air, I tried the range on the mavic air over a straight-line course and found it considerably shorter than it had been before, and when I returned home, under my control, when I commanded the landing the drone drifted sideways into my house? zero wind and in a spot where I always land my spark under way less than ideal wind conditions. I don't have that much experience with the Air but it has always behaved perfectly in the same landing spot. I fly my spark in the house all the time and this drift really took me by surprise. and I have to say I'm a little spooked.
One more thing. The camera control was really slow. I flew my spark several times immediately after and it behaved perfectly and the camera control was instant.
