Kbase Article of the Week: iTunes Store: Can‘t Publish a Podcast →

Apple Support, back in 2012:

Sometimes the iTunes Store can’t publish certain podcasts. If you’ve submitted a podcast using the “Publish a Podcast” page but haven’t seen it published yet, sit tight. The iTunes team reviews each podcast submission. Depending on demand, it may take a week or two before the podcast gets published.

Additionally, here are some other reasons why a podcast might not get published:

  • The podcast’s RSS feed was not available.
  • The podcast’s RSS feed timed out.
  • The podcast’s RSS feed could not be validated.
