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.
Check the episode in Publish. It will most likely be listed as a DRAFT. All episodes scheduled must be PUBLISHED.
I published my episode a couple of minutes ago and it’s not in iTunes:
Podcast publishing is not instant. It can take from a couple of minutes to hours for the episode to appear in iTunes. The episode will appear faster for the subscriber; for non-subscribers, it can take up to 24 hours to appear in the feed (per iTunes). If you still aren’t seeing the episode, 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 their support team.
A lot of apps don’t have good support resources. Here is a list of the ones we could find.(LINK)
