Options plus just had the problem of mouse not flowing reliably so I just turned off flow until I wanted to move files.

Options plus is packed with issues.

1. I use Play/pause and mute on wheel side tilts and now its not reliable. Every time I switch computer in flow the play/pause and mute won't work for about 5 seconds after flowing to another computer. Sometimes it won't work at all after, I do the suggestion of resetting the mouse and it sometimes works. Also might be the same with volume as I use the side button in front of device witch for volume up/down.
2. I feel the flow feature is even more glitchy than Options.
3. Even thought I made sure the keyboard follow mouse feature is turned on the keyboard rarely follows I am constantly having to manual switch. This is didn't happen with non plus Options.
4. I never had to reset a device (mice or keyboards) with non non Options

5. The mouse pointer suddenly jumps to another computer.

I am using 3 M720's one MX keys and a k830. Only one of the M720's is set to flow and MX keys for flow.
