Purchases are usually delivered instantly, but may in some cases take longer.
When such delays occur, it means the purchase is still being processed. There is no need to try purchasing the same pack again - it should arrive soon.
In the meantime please try the following troubleshooting steps:
- Reboot your mobile device;
- Make sure the Internet connection is working correctly. If possible try another Internet connection – for instance change from WiFi to mobile data.
If you still haven’t received a purchase after 24 hours, please contact Apple support. All payments made toward the game are processed by Apple. You can reach them here: https://support.apple.com/contacthttps://support.apple.com/contact
Accidental purchases can be avoided by setting restrictions on your device.
