Many game performance issues (i.e. loading, crashing, missing features, sync-ing of game) can be resolved in the following ways:

(Note: Instructions may vary slightly depending on your device or software version.)

Check your Internet connection
  • Make sure that your device is connected through WiFi, 3G, 4G, 5G, or LTE.
  • If you play through a WiFi connection, make sure your router is on. Additionally, try not to play too far away from it, as you may lose the WiFi signal.

Restart your device

Make sure you have the latest version of your game app installed from the Google Play Store:
  1. Open your Google Play Store by tapping the icon from your homescreen.
  2. In the top right corner, tap onto your profile icon to open the menu.
  3. Tap "Manage apps and devices".
  4. In the Overview tab, tap on "Updates Available" and select the apps you wish to update.

Restart your app by force-closing it:   
  1. Go to "Settings" > "Applications" > "Manage Applications"
  2. Select the app and tap "Force stop"
  3. Return to the Home screen and re-start the game app

Force close unnecessary background apps using the same steps as above.

Make sure that you have the latest software version of your device's operating system.

To check if there is a system update available:
  1. Open your device's Settings app.

  2. Go to "System" > "Advanced" (or "About Phone") > "System update"
If the issue persists, uninstall/re-install the app (*).

(*) Important:  This step may  cause your game progress to reset.

Steps to uninstall / re-install:  
  1. Go to "Settings" > "Applications" > "Manage Applications"
  2. Select the app and tap "Uninstall"
  3. Go to the Google Play Store to find and re-install the app.
  4. Open the app

Note:  You won't be charged again for previously purchased apps if you are using the same Google Play account.
