Confused about Cabin Temp Protection

I have received two messages from my Tesla Y telling me that having the manual AC off is not allowing Cabin Overheat Protection to come on.
I do not have the AC off button in the off position on the COR menu. I do not have the AC auto or the AC manual button on in the Climate Control. in the on position.
Am I supposed to leave the AC manual button on all the time now? That was not necessary last summer when it was hot here, in the 80F range. Now
we are in the 70 range and I noticed that the computer is really heating up. Is there something amiss with my CyberCherry?

Try setting the Climate control screen to Auto; The HVAC will only come on when you are preconditioning or when driving. The HVAC will not remain on after you park unless you select On (when exiting) Camp mode or Dog mode.

The Cabin Overheat Protection settings are on the Safety & Security settings. You can turn Cabin Overheat Protection to On, No AC (HVAC fan only) or Off.

Yes have read the manual and know where the cabin protect features are. I never had the climate control AC on automatic before and cabin protection worked just fine.

Maybe the way that Cabin Overheat Protection functions has an undocumented change, i.e. HVAC must be set to Auto or at least set to be powered on. No way to test it here until next summer, current temperatures are close to freezing.
