I am running the VrVoiceChat sample in the brand new Unity Oculus Integration v1.36 (released 04/23/19), with Unity 2018.2.19f1 and my trusty Rift.
I build the app, then run the .exe directly. When I click "Call Friend", the code calls LaunchInvitableUserFlow and I expect to see a list of friends, but instead all that's happening is that the pointer color changes, my app gets a little greyed out, but no new UI shows up.
One thing is that none of my friends are online at the moment. Could that be what's breaking the UI? What can I do to use this flow but not end up in a broken state?
