Guideline 2.1 - Performance - App Completeness
We found that your in-app purchase products exhibited one or more bugs when reviewed on iPad running iOS 13.5.1 on Wi-Fi.
- An error message is displayed when attempting to complete an IAP transaction.
When validating receipts on your server, your server needs to be able to handle a production-signed app getting its receipts from Apple’s test environment. The recommended approach is for your production server to always validate receipts against the production App Store first. If validation fails with the error code “Sandbox receipt used in production,” you should validate against the test environment instead.
You can learn more about testing in-app purchase products in your development sandbox environment in App Store Connect Developer Help.
