2. 3 Performance: Accurate Metadata
Guideline 2.3.1 – Performance

We discovered that your app contains hidden features. Attempting to hide features, functionality or content in your app is considered egregious behavior and can lead to removal from the Apple Developer Program.

Specifically, we found that your app includes third party payment mechanism, which provides access to external payment mechanisms and enables the purchase of content, services, or functionality by means other than the in-app purchase API.

If you feel that we have misunderstood how your app functions and that your app is compliant with the App Store Review Guidelines, please reply to this message in Resolution Center to explain how this feature works.

The next submission of this app may require a longer review time, and this app will not be eligible for an expedited review until this issue is resolved.

Next Steps

– Review the Performance section of the App Store Review Guidelines.
– Ensure your app, as well as any third-party code and SDKs implemented in your app, are compliant with all sections of the App Store Review Guidelines and the Terms & Conditions of the Apple Developer Program.
– Revise or remove the hidden features from your app. Once your app is fully compliant, resubmit your app for review.

Submitting apps designed to mislead or harm customers or evade the review process may result in the termination of your Apple Developer Program account. Review the Terms & Conditions of the Apple Developer Program to learn more about our policies regarding termination.
