My podcast no longer updates in the podcast app

I host several podcasts, but one of them hasn't updated the last 2 days after I posted it--and pinged it. I'm seeing it everywhere else it gets burned to, except the Podcast app. What's going on--and is there something I can do on my end to fix it? (My other podcasts are updating just fine, so it seems strange that it has to do with the podcast app--esp after I recently did the latest update which was supposed to fix that bug).
