I can't control my brightness from the control centre on my Mac Big Sur 11.40
Hi. I can't control my display brightness from the control centre on macOS big sur. It is a MacBook Pro, 2019. Restarting helps but this happens very often so restarting isn't always fun to do and it is rather annoying. My Touch Bar doesn't work. I'm giving that for repair next week but for now this is really annoying. Can someone please help. Thanks
