Strangley, you can Disembark into on foot mode and access the menu from the Wheel thing and it then works....a workaround, but a pain no less.Even after updating Odyssey 6.01, the upper-left menu does not work in VR mode.
The menu does not work, in which there is a Chat, mission tasks and various messages.
But in Horizons-this menu works in VR mode.
This was reported in tracker by many forum participants.
But the error is still present.
Edit: forgot to say thanks to Arioch for his excellent work in keeping this thread updated and current - I hope the Devs are watching it...
