PLEASE PLEASE DISABLE Auto-Backlight OFF, there is no reason the backlight should turn off so quickly or at all. I and hundreds of thousands have complained about this and there does not seem to be any way unless your a hardware engineer with 10+ years of experience.

This is why we bought the MX Keys in the first place instead of Apples or Mcally or others. I really regret buying this because i didnt know it would turn off so quicly, 5 seconds or 10 seconds is too long even with full battery or having it plugged in. Please fix this because you can include it in the Logitech options software. GIVE US THE OPTION TO TURN OFF AUTO BACK LIGHT. WE NEED ALWAYS ON BACK-LIGHT, WE KNOW THE RISKS OF BATTERY DRAIN.
