Big Sur boot screen Bluetooth keyboard not working - file vault issue

Dear Apple,

can you please work together with your partners such as Logitech to fix the driver issues. It is very annoying to either deactivate file vault or connect from time to time via cable just to login after reboot.

And it can’t be a general problem as you managed to get around it with your own devices.

Anyhow it creates a bad light to Apple too

thx
