I’m using a Mac app called Karabiner-Elements’ for switching input source with the ‘right command key’ just like windows. This is very handy for users using multiple input sources, but I recognized that the remapping function keys on ‘Logi Options +’ app won’t work when my Logitech keyboard is activated on the ‘Karabiner-Elements’ app. And When I deactivate the keyboard, the function key remapping works.

This feedback can’t be a bug, but this could be a suggestion. If it’s possible to change the input source with ‘right command key’ on Mac or ‘caps lock key’ on Windows, it will elevate the foreign user experience a lot.
