Walkaway lock was working completely flawlessly for me. I got to the point where I never looked back at the car to see if the mirrors folded because it never failed to lock. I enabled the horn honk on lock and the second time I walked away from the car after installing 26.3, the car failed to lock. Mirrors didn't fold, horn did not honk, doors did not lock. Yes, I used the phone key to get in the car, not the key card. Yes, walkaway lock was enabled. It simply failed for the first time.
