Are you using MSFS2024 with VFHub 1.3.1 firmware 2.0.1 or 1.3.2 firmware 2.0.2?
I also have problems with VFHub 1.3.2 firmware 2.0.2
You also need to buy a license from VF website for the G1000 panel to work in the Switcho Radios.
At the bottom of the Radios product page there is an option to buy the panel software license.
