I have the latest 7.1 firmware on my MX. I've noticed problems with inconsistent connection to the car even though the other functionality with the iPhone app works perfectly - unlock, honk horn, open charge port etc. Also the car does not open the garage door automatically when leaving the garage but does close the garage 3 out of 5 times when going into the garage. I realize this is in Beta but is anyone else experiencing these problems as well?
