Using the new Logi Options+ between a Windows 10 Asus laptop and a Bug Sur iMac using MX Keys and MX Master 3 the flow between the two often doesn't work properly as it did in the previous Options software. Sometimes it won't flow between at all, other times the mouse will flow but the keyboard will not come along with it. Whereas on the old Options software it pretty much worked perfectly - the new Logi Options+ seems to be very intermittent as to if it will work or not. I have tried changing all the different settings but none of them seem to alleviate the randomness
