Guideline 2.5.2 - Performance - Software Requirements
During review, your app installed or launched executable code, which is not permitted on the App Store. Specifically, your app uses the itms-services URL scheme to install an app.
Please note that while educational apps designed to teach, develop, or allow students to test executable code may, in limited circumstances, download code, such code may not be used for other purposes and such apps must make the source code completely viewable and editable by the user.
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.
Review the Software Requirements section of the App Store Review Guidelines.
Ensure your app is compliant with all sections of the App Store Review Guidelines and the Terms & Conditions of the Apple Developer Program.
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.
If you believe your app is compliant with the App Store Review Guidelines, you may submit an appeal. Alternatively, you may provide additional details about your app by replying directly to this message.
Guideline 4.0 - Design
Your app includes an update button or alerts the user to update the app, but the update button or alert does not link directly to the app’s page on the App Store.
To resolve this issue, please ensure that tapping the update button takes the user directly to the app’s page on the App Store to update the app.
