If the new update is not available to you after the game redirects you to the App Store, do not worry. Please try the following steps:

1. Open the App Store.
2. Tap your profile icon at the top of the screen.
3. Scroll to see pending updates and release notes. Tap update next to the game app.

If the update is still not showing for you, it's because it is on its way to the App Store in your region. Once Apple has pushed the update to your App Store, you will be able to download and install it. Sometimes, this process can take a couple of hours.
