When a message appears indicating that there is a new update for the game, click on 'update" and do not exit the game. A loading bar will appear in the top center of the screen. Wait until the loading bar is complete, and a message will appear, prompting you to re-enter the game. You will have successfully updated the game this way. 

Note:

To ensure the success of the update, it is necessary to use 
a strong and high-quality internet source. Also, make sure you have enough space on your device and delete large files or unnecessary apps.

If you are unable to update the game, first ensure that your base is bound to an account to avoid losing it and to be able to access it at any time. Then, delete the game from your device and reinstall it from the app store.

Important Note:
You may lose some messages in your inbox if you delete the game.

If the issue persists, kindly contact the customer support team immediately.
