I have MX Keys for Business and when connected by Logi Bolt, my backlighting doesn't work. I have the last version of Logi Options+ installed. I don't have the option to disable automatic lighting in the app. When I press keys F3 and F4 which dedicated to backlighting, it says on the screen that I have a light in the room. But even if I switch off all the lighting in my room, it still doesn't work. No backlighting at all. The reboot of keyboard helps for a while and I can adjust backlighting, but after some time it stops working. Have no issues with adjusting backlighting when connected to my MacBook via Bluetooth.
