Guideline 2.1 - Performance - App Completeness
We found that your in-app purchase products exhibited one or more bugs when reviewed on iPhone running iOS 12.4 on Wi-Fi.
Specifically, we are unable to purchase the in-app purchase item.
Next Steps
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.

以上为被拒回复原因，但是服务器我问了，订单验证的时候也判断了沙盒和生产环境情况。我们自己真机也是都没问题。这真的让我摸不到头脑了。有大哥遇到类似情况吗？
