I'm as confused as a milkman at a crematory...
I have a 2 week old Model 3, which came with 2021.35.something...
Also a 22 month old Model 3 which had 2021.36.something, IIRC.
Last Monday or so, both updated to 2021.44.6. Got the single door unlock option and that's about it.
However, comma, no change to the UI we have had for most of the year, none of the stuff listed as being in 2021.44.25, like the light show,
customizable launcher, simplified controls, etc.
The new one came (2 December) withdthe USB in the glovebox, two type Cs in the console well, which power things (haven't futzed with data yet), but I don't seem to have wireless charging. I pinges tesla about the latter, and they said I would be contacted. It's always something nutty going on.
Not sure who to believe anymore, except that I am over the moon with my new Tesla, as I still am with the first two. Kind of like Forrest Gump and his box of chocolates, I guess...
