It looks like many of the training sessions are not doable in VR.
It is like the SIM is expecting certain input that can only be done while NOT in VR.
This is very disappointing, but not surprising. I would suspect most testing done not in VR because that may be the most common use case.
I hope they fix it for VR because I only like to play it in VR and was hoping to do the full training and career mode in VR.
For now I have to keep jumping in and out of VR to get past points where it gets stuck.
There are so many I don’t know how to report it all. Maybe they could add some telemetry to gather information about when the sim gets stuck in training missions.
