Same for me
.I tried it out just now and after about half an hour, I could not engage Autopilot with FSD enabled. When I turned FSD off to go back to the way it used to be, it would allow me to engage Autopilot, but it would ask me to take control after only a few seconds up to about 1/2 a minute with some loud beeps and the red steering wheel. We'll see if it's feeling better in the morning. If not, I might do a camera calibration. Already parked and rebooted. Can't think of anything else to try to get me re-enabled. If anybody has other ideas of what to try, let me know.
