media keys not working properly on Big Sur
I've just upgraded to Big Sur on my three year old iMac. Since the upgrade the following media keys do not work:
play/pause (F8), rewind (F7) and fast forward (F9) do not work for Apple Music or VLC, although they work fine for apple podcasts and YouTube videos in safari, which indicates that it is not a keyboard problem.
Mission Control (F3) and Launch Pad (F4) do not work at all.
The more universal controls such as dim (F1), brighter (F2), but (F10), volume down (F11) and volume up (F12) still work fine.
Is there some configuration I need to change to make these keys work again as everything was working fine on Catalina? Can anyone advise me on how to fix this?
