Select Vio as your payload in WGC before booting (so you do not have to reboot after)
Connect your Vio to the quick attack via the gimbal
Power on the drone and open QGroundControl and allow parameters to load fully
Once loaded close QGroundControl and open WisprGroundControl, allow parameters to load and you should have a working stream and you will have full function of the roll wheel.
