You can sort your episodes by number, in ascending or descending order.
In the "Number" field under "Edit Episode --> General" you can enter a number (not 0) to specify in which order your episodes should be sorted in the feed for a serial podcast. For an episodic podcast, the number is irrelevant, but you can optionally include it in the feed.
Important to know: We use the sort number in our Analytics portal as a unique attribution of episode views. If you change the number after publication, the statistics will get messed up and need to be adjusted. In this case, please contact us: email@example.com
