If you've made purchases before, try these steps:

• Use a strong internet connection (Wi-Fi or LTE).
• Restart the game and let it load for a minute after all the events load up.
• Check your App Store or Google Play for notifications/errors.

If this is your first purchase:

1. Check if your payment information is correct. If there's an error, cancel the transaction and try again.
2. Make sure the app store accepts the payment option.

If the problem persists, contact App Store or Google Play support for more help.
