Unfortunately, some players are currently unable to download the latest update (version 4.1) on Windows 8.1 PC as it does not appear in the Windows Store due to issues on Microsoft’s end.
We regret to announce that we can no longer guarantee that new versions of the game will be immediately available to download from the Windows Store on Windows 8.1 PC.
We would recommend playing the game on Windows 10, or a device that runs an entirely different operating system (such and iOS or Android) if you are having problems updating or playing the game on Windows 8.1.
If you have any questions about this, or require assistance transferring your account onto a different device, please send a ticket to customer support.
We apologise for the inconvenience.
