When I try to take off, motors on the port side spin, but those on the starboard side don't. Using RC Pro controller. The only thing I've done differently is use batteries from my Air 2 in the Air 2S. I've since refreshed firmwares. Still get the Motor Failure message. It did this once a week ago, twice, taking off crooked. But worked fine since then until today.
I see Air 2 uses V01.01.0920 while Air 2S uses V01.01.921 firmware?
