title: Missing certificate for authenticated push notifications - Dev center
body: <p>I have converted my WP7 app to WP8. After upload to dev center (Microsoft marketplace center for developers) it says: 
  Missing certificate for authenticated push notifications: Certificate for authenticated push notifications</p>
  
  <p>But I have no more options than before. <strong>I have no push notifications in use</strong>. </p>
