I am trying to rebind the toggle mute mic key from M to \ but every time I exit / reenter the options the key setting is set to unbound and the only thing I can do is to reset the config settings to default. (even when I try to manually reset the keybind back to M the keybind is set to unbound on reentering the settings).
Hero specific control setting are saving ok, it is just the settings under the communication tab in the controls settings that is giving me this problem.
I tried deleating my settings folder and reinstalling the game with no luck. I have also tried resetting all keybinds back to default aswell.
I am playing on the battle net client of overwatch
