So my bluetooth keyboard function key hasn't been working for a while, the built in one works fine. I bought a new apple keyboard to try and fix the problem but turns out its my laptop. I also noticed that where the bluetooth settings used to show battery levels for apple products, it no longer does.
All the F1-12 keys work fine but the function key its self doesn't work at all or in combination with other keys.
In the bluetooth settings it says no battery but at the time the keyboard batteries were full.
I have tried basic things like un-pairing and pairing again, also some commands to unload and load bluetooth files.
