While I had problems with the app and MCU1, using the key fob worked every time- in the event you have not used this function before, it's a long hold on the middle of the fob, then a press on either end to indicate the direction. The same can be said for auto-park while in the car, which is just putting the car in Park, waiting a beat and double-tapping Park again before indicating the direction and exiting the car. I would then use the fob to get the car out of the garage.
