Just had my MBP 14" for the last few days. On 2 occasions after waking up, the screen failed to automatically adjust its brightness even though I was in very dim lighting to the extent that I could hardly see what's on the screen. I had to manually increase brightness using the function key. Anyone else having this issue? I have both automatically adjust brightness and True Tone checked in the display settings.
 
I don't think I follow. When you're in dimmer lighting, the screen should automatically dim as well. It gets brighter when the light you're in gets brighter. If you keep it at low brightness during the day, at night it might get pretty dim. (I don't like the way auto-brightness does that, so I don't use it.)

That makes sense but its so dim that I can't even see what's on the screen. Is that normal?

I could be wrong but auto brightness uses where you have it set at as a baseline. So if you have brightness turned clear down. It won’t get very bright. I usually keep mine on my iPhone around half brightness. Seems to give AB a little more room to breath.

Hard to say without knowing more about how you have it set, and what the lighting changes are like, but it doesn't surprise me.
 
Just for some perspective, I also have a M1 MacBook Air which never has this issue. Everything is right when you wake it up regardless of surrounding lighting. It is set to the same display settings as the MBP.
