Guideline 2.1 - Performance - App Completeness
Your app or its metadata does not appear to include final content. Specifically, your app contains placeholder content.
Please see attached screenshots for details.
Next Steps
To resolve this issue, please review your app and metadata to ensure that all of its content is final.
Since your iTunes Connect status is Metadata Rejected, we do NOT require a new binary. To revise the metadata, visit iTunes Connect to select your app and revise the desired metadata values. Once you’ve completed all changes, reply to this message in Resolution Center and we will continue the review.
NOTE: Please be sure to make any metadata changes to all app localizations by selecting each specific localization and making appropriate changes.
