Upgrading to v1.03 on a new device (or the app has been reinstalled) please use these steps to get your existing cloud save.
This is only if you had previously connected your Facebook account with the game through the OpenKit system which has been removed due to the service closing.
Start the game
Select Options
Select Cloud Save
Select Yes in the popup dialog
Log into your Facebook account. If you already logged into your Facebook account via device Settings, this step may be skipped.
Upon completion, you should then be able to download your previous cloud save and continue playing.
