Touch ID won't wake from sleep in Big Sur
I have a new MacBook Air 13" which has worked fine until I updated from Catalina to Big Sur. Now touch ID works except for waking from sleep. I have tried deleting the fingerprint and reloading it and it works first time and no more. I have tried unchecking 'unlocking your mac', rebooting and then checking it again and nothing works. It will wake by typing the password but that defeats the object of touch ID.
