Keeping the application updated is important to be able to access the latest features and also to avoid inconveniences within the game.
To make sure you always have the latest released features, we recommend activating Auto-update in the Store settings.
Go to Settings > iTunes and App Store > Automatic downloads and check the "Apps" option.
Enter the "Play Store" application. Once there, you will see an icon with three horizontal bars in the left sector of the search engine. Press it and enter Settings and select "Update applications automatically."
You can also update the applications manually by searching for them in the Store and selecting "Update".
Keep in mind that sometimes you will have to find the game in the store, select it and once selected you will see the available update.
