Z3 Dongle not detected after firmware update

Z3 Dongle not detected after firmware update

So I have the new Z3, and within 15 minutes of using it, it wanted to update both the dongle and the mouse, so I update the mouse, since it asked for the mouse to be wired, I unplugged the dongle and updated the mouse. Now the mouse doesnt connect through the dongle. and the software doesn't recognise the dongle on its own, meaning my mouse is now wired or bluetooth, due to the dongles firmware being out of date.
I would like the option for the software to either be able to recognise the dongle on its own, or downgrade the firmware on the mouse.
