Ah, the missing episode dilemma! There are a few iterations of this - please find the situation that describes you below.
I scheduled my episode and it hasn’t been published!
I published my episode a couple of minutes ago and it’s not in Apple Podcasts or Spotify!
Podcast publishing is not instant. It can take from a couple of minutes to hours for the episode to appear in Apple Podcasts or Spotify. The episode will appear faster for the subscriber than for non-subscribers, and can take up to 24 hours to appear in the feed. If you still aren’t seeing the episode after 24 hours, email firstname.lastname@example.org.
My episode is missing from <insert app name>
First thing to do is check other podcast platforms. If your episode is only missing from one, then you will want to reach out to that apps respective support team.
