Answer 1

2.1 App Completeness

Submissions to App Review should be final versions with all necessary metadata and fully functional URLs included; placeholder text, empty websites, and other temporary content should be scrubbed before submission. Make sure your app has been tested on-device for bugs and stability before you submit it, and include demo account info (and turn on your back-end service!) if your app includes a login . If you offer in-app purchases in your app, make sure they are complete, up-to-date, and visible to the reviewer, or that you explain why not in your review notes. Please don't treat App Review as a software testing service. We will reject incomplete app bundles and binaries that crash or exhibit obvious technical problems.
