Restoring your purchases will make any levels that you've purchased show up. Using the same ID for your device's app store as the one that purchased the levels:

1. Select the "Snowflake" icon in the top left corner
2. Tap on "Restore Purchases"

Note: The "Restore Purchases" option does not cause power-ups to reappear. For assistance with other missing purchases, please reach out to the support team via the "Email" button below.
