If you had your levels progress on an old device that connected to Facebook in the game and are trying to sync this progress to a new device, please reconnect your Facebook account in the game on the new device.
If you're having difficulties with your devices not syncing correctly, please update all your devices to the latest version of Book of Life. When new levels are released, all devices must be updated for them to load correctly.
Please note that your data is backed up only by connecting to Facebook. If you delete the game or lose your device without having connected to Facebook, you will not have a saved game.
If your games are up to date and your level progress is still not correct, or if you did not have your game previously connected to Facebook, please submit a support ticket in the game, by tapping the "gear" icon on the map screen, and then "support," or you can open an online support ticket here.
