If you've recently changed your intro/outro file and are wondering if it will update across all your episodes, the answer is yes! This is a great feature that allows you to easily update your podcast's intro/outro without having to manually change it for each episode.

If you've changed your intro/outro file but are still hearing the old one on a specific platform, it is likely due to user cache. This means you'll get the same version of the audio file for ~72 hours when you are listening on the same device. So if you've recently listened to the episode on Acast from your computer, you'll get the same version for a couple of more days. If you listen on a different device, however, (as a new listener) you should get the updated file.

If you want to exclude the trailer episode from the intro/outro, you can upload it as a "Trailer" type on its own. You can learn more about it here.
