Sorry for the inconvenience. Can you try the following?
If the VR app does not detect the companion app, try connecting your headset to your PC while the companion app for about 10 seconds, and then open the VR app. This will do a manual discovery.
If you updated from another version and have issues, delete this folder: C:\Users<YOUR USERNAME>\AppData\Roaming\Supermedium
I hope it works!
