I'm using Flow with an MxMaster3 and an MX Keys PT Layout. Paired with 1 windows 10 pc, 1 windows 11 pc and 1 Apple Macbook Pro (M1 cpu).
Using Flow between the 2 windows PCs works flawlessly, but when moving into the Apple desktop, the keyboard doesn't follow the mouse. Meaning, the mouse moves into the Apple Macbook screen but the keyboard remains inactive unless i press the specific physical button to switch.
