The Flow doesn't seem to work. I have two windows computers connected to the same network (mesh). One is a laptop connected wirelessly, and the other is a desktop, connected via ethernet cable to one of the mesh nodes. Options+ is installed on both machines. The compatible mouse/keyboard have been paired with the devices. Do both machines have to be on Wifi (i.e. exactly the same method of connection) for this to work? If so, that isn't specified in the instructions.
