Once you make a purchase, the items should be credited to your account immediately. If this does not happen, we recommend the following:
- Force close the app (How to force close the application on iOS?).
- Re-open the app and check if you have received the items you purchased.
If the purchase has still not been credited, we recommend that you contact the Apple Store directly explaining the situation so that they can help you resolve the issue, as they process payments directly, and we do not have access to the purchase database.
