If you think I'm exaggerating: the car is unable to deal with two drivers having different settings (doesn't recognize keys, settings get mixed up), the rear camera view does not come up about 30% of the time, and if you try closing two windows simultaneously, sometimes one will go up and the other down.
Their app is totally useless for anyone but the "main" driver (bizarre concept), for whom it is just buggy and shows wrong information and doesn't always do what you ask it to.
VW really dropped the ball on software quality.
