We sincerely apologize for this issue.
Purchases of Gems are reflected in the game according to data transmitted from the App Store. Unfortunately, this can in some cases cause a delay before the purchase is reflected in the game.
If your purchased Gems are not reflected in the game, we first ask that you please restart the app.
If the purchased Gems are still not reflected after restarting the app, please reach out to our customer support team at "Contact Us."
Please provide the support team the necessary information, and we will investigate the issue.
