It can take 24-48 hours for a new Episode to appear in many third-party services, and unfortunately there’s no way for you to manually make the process go faster. But rest assured that if the Episode appears on your Podcast’s website, then it is available to everyone, including your subscribers.
If you’ve waited more than 24-48 hours and not seen your new Episode appear, we recommend that you contact the third-party service (iTunes/Spotify/etc.) directly to see if they can refresh your feed. As long as the Episode appears on your Fireside website, it has been published correctly and is available to all third-parties.
As much as we’d love to help, unfortunately there’s nothing Fireside can do to force a third-party service to refresh your feed.
