Hello, my app was rejected.It is a music player and downloader. With built-in browser (WebKit) user can search websites with music and download it only if websites allow to do it (there is button to download). So, user cannot download music with my app, for example, from Apple Music or YouTube.In Resolution Center the message with reason for rejection is:Guideline 5.2.3 - Legal - Intellectual PropertyYour app allows users to save or download music, video, or other media content without authorization from the relevant third-party sources.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 Intellectual Property 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.Guideline 5.2.3 - Legal - Intellectual Property:5.2.3 Audio/Video Downloading: Apps should not facilitate illegal file sharing or include the ability to save, convert, or download media from third party sources (e.g. Apple Music, YouTube, SoundCloud, Vimeo, etc.) without explicit authorization from those sources. Streaming of audio/video content may also violate Terms of Use, so be sure to check before your app accesses those services. Documentation must be provided upon request.My answer in Resolution Center is:My app cannot save or download media from third party sources (e.g. Apple Music, YouTube, SoundCloud, Vimeo, etc.). App includes a usual browser like Safari. With this browser users can search music in google and download music from websites that allow to do it. For example, you can go to Apple Music or YouTube site, but you cannot download any content, because these services do not provide this feature (there is not button to download). So, my app does not allow users to save or download music, video, or other media content without authorization from the relevant third-party sources.And, finally, their answer:Thank you for providing the information.Regarding Guideline 5.2.3, your app allows users to save or download music, video, or other media content.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.We look forward to reviewing your resubmitted app.Can you help me in this situation? Their last reply repeats the information from the first message, as if they didn't understand my explanation or even didn't read it.
