I've just tried the Oculus Store version of VRChat, and I'll be sticking with the Steam version for now because of one big issue. On the Steam version, the Oculus Dash menu overlays VRChat. You can still see what's happening around you in-game, and you can still move your hands. In the Oculus Store version, the dash doesn't do this. You can't see the game world at all while it's open, it takes you to a white void until you close it. Please add support for Oculus Dash so I can still see the game world around me. I often use it while chatting with people.
