Is anyone else with AP2 on 8.1 (Model S) experiencing "Cruise Not Available"? The release notes say that while AP2 is recalibrating for the high-speed AP, that low-speed would be available. In my case, after the upgrade the car no longer sees lanes, and attempting to engage low-speed AP or even TACC gives a result of "Cruise Not Available". I think it might be a result of re-calibration, but the release notes specifically talk about keeping low-speed AP during the process, which would seem to include TACC capability. I've reached out to a few contacts but wanted to know if anyone else had experienced it.
