Before we can continue with our review, please confirm that this app does not violate any of the above guidelines. You may reply to this message in Resolution Center or the App Review Information section in iTunes Connect to verify this app’s compliance.
Given the tendency for apps of this type to violate the aforementioned guidelines, this review will take additional time. If at any time we discover that this app is in violation of these guidelines, the app will be rejected and removed from the App Store, and it may result in the termination of your Apple Developer Program account.
Should you choose to resubmit this app without confirming this app’s compliance, the next submission of this app will still require a longer review time. Additionally, this app will not be eligible for an expedited review until we have received your confirmation.
