So I recently purchased an MX Keys and MX Master 3 to use at home for work, and whilst I can use the unifying software so they both connect to the one receiver, I cannot get this damn software to work. It's absolutely frustrating because I really like the keyboard and mouse, but I want to be able to assign things to buttons, etc. I've searched and apparently it's a very known issue. What basically happens is: I'd install Options and it'll work fine after installation, but it won't detect my devices. I click add device and it says there's no unifying receiver (which of course there is). If I close the program and reopen, it just stays on a blank screen and hangs indefinitely. Tried uninstalling Options, uninstalling USB drivers, installing older version, but the same thing happens. It's just so buggy. Anybody have either of these devices and can get Options working on Windows 10?
