3.2 – Apps with placeholder text will be rejected
Your app or its metadata does not appear to include final content. Specifically, your app contains placeholder in marketing description.
Please review your app and metadata to ensure that all of your content is final.
Since your iTunes Connect Application State is Rejected, a new binary will be required. Make the desired metadata changes when you upload the new binary.
NOTE: Please be sure to make any metadata changes to all App Localizations by selecting each specific localization and making appropriate changes.
Additionally, your app declares support for audio in the UIBackgroundModes key in your Info.plist but did not include features that require persistent audio.
The audio key is intended for use by applications that provide audible content to the user while in the background, such as music player or streaming audio applications. Please revise your app to provide audible content to the user while the app is in the background or remove the “audio” setting from the UIBackgroundModes key.
