Missing Moon Rocks
If a pack you paid for has not arrived, reopen the app: it tries again to add purchases Apple has confirmed. Do not buy the same pack again. A purchase waiting for approval, such as Ask to Buy, is added after Apple approves it. Moon Rocks are a consumable purchase, so they are not restored like a permanent unlock, and a pack bought on another device is not added here.
Your saved port
Your port is saved only on your device and there is no cloud save. Deleting the app can remove your port and your Moon Rocks, including purchased ones, and Delete my data in Settings always does. We cannot recover them.
Refunds
Purchases are made through Apple, so refund requests go to Apple.
