Via the developer options refresh rate counter, I can see that my phone right now is stuck at a constant 120hz on the adaptive refresh rate mode. It used to appropriately switch between 120, 60, and 48 depending on the content and if the display was static but from now it just seems to be frozen at 120hz, even on the Aod.

there is a simple workaround
s21 ultra screen adaptive refresh wont work unless you increase the brightness

above maybe 20% if you dont like the higher brightness specially in night

just go to accessibility and toggle extra dim and move the slider to max

and thats it the phone brightness will be above 20% and that will activate the adaptive refresh rate and the extra dim feature will make it look like you didnt raise the brightness

Adaptive refresh rate does not work under a certain amount of ambient lux. Anandtech covered this last year and the year before regarding the note 20 ultra screen too.
