Logi-units in Mac OS 12 beta is a mess. I can connect only one unit (MX Keys or Mx Master 3). If I connect both one only one shows up in Logi Options+ or none of them shows. I then have to reconnect one of them to make it work properly. If I have the keyboard connected, and then connects the mouse, the functionskeys on the keybaord stops working (volume up and down and others).
