I'm having trouble with Flow between my Mac and PC. I have the MX Master 3 for Mac connected to my Mac via Bluetooth and to my PC via the Logitech Unifying Receiver and the pointer will not move between the two machines. If I connect my mouse to the PC via Bluetooth, the connection is unstable, probably because I have a very cheap little Bluetooth dongle to provide that connectivity. Is flow supposed to work between the Unifying Receiver and Bluetooth? In Logi Options+ on both machines, I can see that they are both on the Flow network. The pointer just won't move between them whether I'm trying to use the control key or not. In fact, I'm not sure I ever got the control key to work.
