Welcome to the Candy Crush Saga Community
Do you have a question or need help with your game? Ask the Community.
When you give an app access to your Facebook account, that access expires after 90 days. The app then loses access to your account, which may affect your progress and friends list.
You can check which apps are active, expired or have been removed from your account by clicking this link: https://www.facebook.com/settings?tab=applications
If the game is listed as ‘expired,’ it means your friends list and progress may not sync with the game.
Click ‘Renew Access’ to reactivate the app’s permissions.
If you still have the same problem after doing this, I would ask you to reinstall the game app. To do this you lose all stored boosters. But your problems should be solved.
Please let me know.
