I have a Model 3 Performance. The text readout did work for a while, then it stopped. I haven't been able to bring it back. Unpair, re-pair, make sure bluetooth notifications are on, etc. Texts just don't show up any more.
My car is a little psychotic, perhaps :-). Probably a coincidence, but I also can no longer get the dashcam to work. Tried an exotic solution first (Pi Zero emulating a drive, with WiFi uploading at home), but it wasn't reliable, so then I switched to just a regular USB drive (adapter + high endurance microSD card), which worked for a month or so, but has stopped working and I haven't been able to figure out why.
I'm hoping the newest update with the Sentry updates will fix that last problem, since apparently it can format the card now. Though I did hear something about the last release also screwing up sentry for some people, so who knows. I'm at 2020.16.2, so there's at least one more point release that I haven't gotten yet.
Have you tried a full power-off, waiting 5 mins, then powering it on? I am not talking about holding the two steering wheel buttons to do a quick reboot, I am talking about a full power-off through settings.
I've read in some recent threads that this method ended up resolving a lot of really weird and random issues like what you described.
Interesting, I had a brief period where my M3 LR AWD would "forget" that I had enabled text message synchronization with my phone (a recent-model iPhone) and I'd have to open the bluetooth menu and re-enable it, but I haven't really had any ongoing issues with either message readout or the dashcam.
