Hi. I updated to Big Sur last night (Nov 15th), and I am unable to adjust the screen brightness using either the function keys, command center, or system preferences. In all cases, the tiles move appropriately, but there is no actual change in brightness. Seems to be stuck on full bright. I’m using a 2014 MBP.
Is there anything I can do to fix this issue?
Thank you!
