Wasn't successful getting this to work. Headset is connected to the app, all green. TV, Smartphone and Quest are all connected to the same WiFi.
First, I tried to cast to my Nvidia Shield (nothing happened). According to the app there should be some sort of confirmation screen in the headset, which isn't the case.
Same when trying to cast to the phone itself (Samsung Galaxy S9, Android Pie).
So I tried it the other way around and started sharing from inside the headset. Same thing, nothing happens on the phone. Except one time, where I just got a black screen.
Did this work for anyone?
BTW: Would be great if you could alternatively stream directly to the phone (WiFi Direct). So you could share someone's experience if you are not at home. Currently, it's not possible to assist someone without being connected to an external WiFi.
