Hi - I use (and LOVE) the MX master 3 for mac. I usually have the forward and backward buttons setup in chrome for switching between tabs. This seems to have stopped working (now toggles between elements on the page). I tried manually entering the shortcuts (cmd+opt+fwd/bwd) but it will not let me use the fwd or bwd keys on my keyboard in the shortcut. Please can you fix this? Thank you, A Grateful User.
