I'm using Flow between a Mac and a PC, and about 50% of the time that I "drag" the mouse from one computer to the other, the keyboard/mouse don't map properly. The main left/right click buttons on the mouse do different behaviors and the Control/Command buttons on the keyboard do different behaviors. I fix it by dragging the mouse back to the original computer, and then back over, and that usually resolves it. It happens going both directions, PC to Mac and Mac to PC. This is a big annoyance, especially for a keyboard/mouse set (MX Keys / Master) that costs $200+!
