I factory reset too on 16.2 last night and everything is running smooth as silk, took like 30 minutes, because I maintain notes of what I set everything to and some history of changing some things to see if it helps on things like phantom braking. Also at someone's suggestion I left my TeslaCam USB stick out as he suspects it could bog things down and cause trouble.
I think folks need to not confuse the automatic opening of the doors with homelink as you drive up vs hitting the transmit button [which is what the OP is complaining about here] (manual or automatic) and nothing happens. Two completely different issues.
By the sounds of you other posts on this, still not completely clear, it's the automatic open part that is not working well for you. Please clarify.
I also gave some suggestion to help on that because after factory reset the GPS is borked for a while and you DON'T want to setup HomeLink until GPS is solid again. Even if you don't use automatic door opening it politely drops the menu down when I approach my home. And that is working perfect too.
I've factory reset 3 times in 8 months and never had any issues and it didn't fix anything major but feels snappier, back up camera tends to come up instantly more often, sleeps a little better. But that could purely be placebo effect. I've also been lucky. Never a reboot (while driving or at wake up), never lost audio bass, never lost audio, and currently 1 second max delay on backup camera. But I know those are very random issues and my lack of them might be pure luck and nothing to do with a factory reset now and then.
It is tedious to factory reset. It's no big deal though.
But if for some reason you can't re-setup homelink I'd want to find out why. Maybe the car has an issue that needs to be addressed or perhaps the door opener needs a factory reset
I always like to know I can reset/reconfigure any time I need to. I kind of lost track all the changes I made and why I made them. Might be as simple as a low battery in your clicker. I'm sure you'll figure it out.
