FWIW, pretty much the only issue I've had in months with my 2025 AT (2.9.0) is occasionally Bluetooth "hangs" when I get in the car (always use Carplay). When it tells me something like "turn Bluetooth on to use Carplay" I notice Bluetooth shows off in the pilot panel (which I have never explicitly turned off). Hitting the slider to turn it on results in a spinning white circle that eventually fails to turn on. No amount of retries helps. But, doing a Air logo (or x-mic-brake) reboot immediately fixes it (so much so Carplay comes up almost before the Infotainment completes its reboot).
It's happened maybe four'ish times total over a period of maybe 6 weeks. So it's been a mild irritant at most and is easily fixed in 90 seconds. That may be something to try for people where suddenly Bluetooth goes inactive (although that most likely won't help folks that show it is active and have other connectivity issues). But, if you have the "little white ring circling" when attempting to turn on Bluetooth, it might fix it - at least for a while.
