The bug actually started happening when I created the App Lab version - so it has something to do with the app trying to call back to the Oculus backend and something failing there - so even the very first version would still see the problem. The tricky part is that I don't have an account where the bug reproduces, so I've been having trouble finding out what exactly is causing the problem. I've poked at the login sequence a couple of times to short circuit it (so it's not calling back to the Oculus backend), but apparently that's not working.
