title: Closed testing getting item not found
body: <p>I have an app that I want to test with a google group of testers. I have all of this set up, enabled any domain etc.. I waited a week for the app to be published (it is now published), shared the opt-in link with the google group but after opting in testers are unable to view the app - it just says 'item not found', despite their devices (and over 8000 more) being supported. I tried waiting for another 3 days but nothing has changed. The testing devices all have a sole google account.</p>
  
  <p>I have no idea what I'm doing wrong - any help would be appreciated.</p>
