Just FYI... I have 2 computers, basically new running Intel i7 Gen 14 chips. I have the MX Mechanical keyboard and the MX Master 3S mouse. Sometimes when I use the flow (holding the Ctrl button and dragging my mouse over) it works without any issues. But a lot of times, it won't work and I have to use the button on the bottom of the mouse and the Key on the keyboard.
Both computers are ASUS, one is custom, one is standard. The custom has 64 G of memory (32 G in the standard).
If I open the Logi Option on both computers and check everything, they are both correct and might work. Sometimes it takes a reboot.
I love the ability to control multiple computers, and I love my Keyboard and Mouse.
Just wanted to report this issue.
