Flow is having difficulty connecting my 3rd computer. When setting up Flow, it seems like Options+ will only recognize the first 2 computers. Using MX Master 3 and MX Keys with 1. Windows 10 (ethernet), 2. MacBookPro latest Big Sur (Intel, ethernet), 3. Mac Mini latest Big Sur (Intel, wifi). All are on the same 192.168.1.x subnet. Also Flow refuses to traverse to my Windows computer from either Mac.
