If you are not seeing friends that you recently added to your Facebook profile, we recommend that you unlink and re-link your profile from the Trivia Deluxe account.
Keep in mind that you must take this action directly from the social network by entering Settings and privacy > Settings > Permissions > Apps and websites. Once there, select Trivia Deluxe and press the "Delete" button.
Then, you can link your account again from the game to update the information. You will find the "Reconnect" button next to the Facebook logo and the legend "Reconnect your account" on your home screen, below the "Play" button.
