Rear View Mirror Not Dimming

[M3 Crew Dragon]

My 2020 Model 3's rear view mirror neither dims automatically nor offers a switch that would allow me to manually dim the mirror. Am I missing something, or does mine not have that feature? Surely there would be a way to manually dim so I'm not blinded at night.

Thanks for any help...

(I apologize if this has been posted and answered elsewhere but I could not find an answer.)

The center one should auto dim. The side rear mirrors do not, though apparently they’re coming back so who knows anymore.

Thanks. It is the middle (windshield mounted) mirror and it will not dim so I suppose I'm heading to the Tesla service center.

Are you saying the mirror physically moves, or that something internal changes the reflection, because my mirror has never moved. I just assumed something happens internally.

Yes the mirror dims by electrochromism.
