Just an update: My co-worker was successful at logging in on the CenarioVR App on the Oculus Go and he was able to launch the published scenario I shared with him.
As for the iOS app I haven’t gotten anywhere. My update is that when I launch the App now I just get a white screen. The only way I can get back to the login screen is to delete and reinstall. But then I still can’t get it to login and I’m back to the white screen when I relaunch the app.
