If you're having a problem with the Showgoers glasses not showing up, sometimes this can be solved by opting out of "Test Participation" in your Netflix settings. What does this mean and how do you do this?
Sometimes Netflix will build new user interfaces but before rolling out to everyone will show it to only a small minority. Occasionally, this will break Showgoers. Fortunately, Netflix gives you the ability to turn this off so that you only get the normal stable version of their UI.
To turn this off, you go to your Netflix account settings.
Click "Test Participation".
Set the option to "off" and click "Done".
