i tried to test the Flow feature on my MX master 3s, but I am encountering a bug or a problem I think.

I have my macbook connected to device 2 in the mouse and my windows laptop to device 3 both using bluetooth. when I am connected to my macbook, it switches to the windows without any problem, ie. device 2 to device 3. but it does not switch from my windows to my macbook, ie. device 3 to device 2. It switches from device 3 to device 1 and I can see that from below the mouse that it is at device 1, I Don’t Know if this is a bug or not, but I’m sure that it’s possible to do this switching.
