I have the MX Keys and MX Master 3 setup. The Flow feature is amazing, but id like to report a bug the is frequently happening with me. Sometimes when i reach the corner of the screen and change to the other computer, strangely my MX Keys is not following, so i end up with my mouse controlling one computer while the keyboard is still stuck on the other computer. Been so, when i use the keyboard (start typing) the inputs are sent to the wrong computer, resulting sometimes in a little bit of a mess with my work on the other computer. To fix the issue i have to manually change the computer using easy-switch buttons on MX Keys, or use the mouse to reach the corner of the screen again to return to the other computer (where the keyboard is working), fix the mess, and then reach the corner again to go to the desired computer. Experienced this issue with both Options and Options+. Thats it, i hope to see this fixed soon. Thanks for now!
