Why can't I see old episodes of some series?
Player FM keeps in sync with the publisher's feed, so if old episodes aren't there, it may be because the publisher removed them from their feed. We might later experiment with keeping them around, subject to publisher approval. But it would still need a warning flag because we cannot guarantee the publisher still serves the episodes if they've removed them from their feed.
They are often served and only omitted from the feed to keep it small. Yet other times, they will have removed the files from their server.
