Don’t see your Facebook friends on the Disney Emoji Blitz Leaderboard? Make sure you (and your friends) have set the App Visibility in Facebook to "Friends":

NOTE: While you may see your Facebook name, Emoji Blitz displays only your first name and the first initial of your last name to other players.
  1. In Facebook, click on the down arrow in the top right and select "Settings".
  2. In the Settings menu, click on "Apps" in the left column and select "Disney Emoji Blitz".
  3. Click on the drop down menu in the top right; select "Friends" and click "Save".
You should now see your Facebook friends that are playing Disney Emoji Blitz on the Leaderboard.
