If you are having trouble seeing your most recently published episode in Apple/iTunes, this could be an Apple feed update issue.
While the episode is available immediately for subscribers using iTunes or the Apple Podcast app, the Apple database, which powers the Apple Store, can take some time to update. Apple says anywhere up to 24 hours, but we generally see updates in less than 6 hours.
If it has been over 24 hours, we recommend reaching out to Apple directly at firstname.lastname@example.org.
Other things that may be helpful:
-If you have access to iTunes site manager or Podcast Connect we suggest refreshing the feed there. That's been known to speed up the Apple database.
-If using a Feedburner account, ping or re-sync the Feedburner feed. Even though the Feedburner feed is up to date, this trick has occasionally worked in speeding up Apple database lag.
