My sister just picked up her Model 3 (with 2018.24.8) last week. I've had mine for a couple of months (2018.21.9).
My garage door opens when I approach and closes when I leave, just as it's supposed to. Hers does not.
It opens fine when she approaches. The HomeLink indicator shows "Opening in 10 feet" etc, and then the door opens. But when she leaves, it never even shows the HomeLink indicator that closing is pending. She can reach up and touch the icon, then touch Home, and it closes just fine, but for some reason the car doesn't seem to know that she is leaving home.
Any ideas, suggestions? We reprogrammed the opener, and reset position and distance a couple of times, to no avail.
