Persistent 500 Server Error / 540 Vehicle Server Error

Still experiencing this. My app said "Last seen 23 days ago" this morning. But, I just got pushed an update. I'm now on 2021.24.28. Looks like it's been rolling out to MCU1 folks over the past few days. I updated real quick and as of now I'm still connected. We'll see what happens.

My 2020 Model Y said it needed an update before Feb 22nd or the cellular would stop working. Hopefully 2021.24.28 does the same thing for my Model S (it showed no such warning, though). TeslaFi indicates the first known install of 2021.24.28 actually happened on 2/15/2022, so it seems to be a new build from an old codebase.
