The last option we have to try and resolve any issues is to is to delete the app and reinstall it.
Before deleting the app lets make sure that all your progress is backed up.
If you usually play connected to Game Center, then make sure the last level you played was whilst you were Game Center connected.
You are now connected to Game Center, and can use it to save your progress and play across multiple iOS devices.
Once your progress is backed up you can now uninstall the game. Please also note that any boosters or extra lives stored in the game may also be lost during this process.
To remove an app from an Apple device, touch the app and hold your finger down until all the apps start to shake. You will see a circled "X" in the upper left corner. Tap it to delete the app.
Now reinstall the game and restore your progress via the Game Centre.
