‘Always on’ Apple Watch series 8 don’t work

From the bottom of your watch face, swipe up to open Control Center. Look for the icon with two face masks, which is theater mode. If it is highlighted, tap it to turn it off.

OK. Do you by chance have a half moon at the center top of the display showing? If you do, you may have Do Not Disturb turned off, which you can turn off from the same Control Center.

I'm sure they'll get you taken care of.

Curious...

Is the screen black?

Ok. It's sounds like you're going down the right road then.

Some people come here wanting their screen to stay bright and not go dim. I just thought that I'd double check ;-)
