Is Spotify showing your episodes in the wrong order? First check in the Springcast PRO dashboard under 'podcast settings' how you have this set for your podcast (Episodic or Serial).
Episodic means that the episodes can be listened to in non-chronological order and is shown in app from newest to oldest episode (based on publication date). Serial means that the episodes should be listened to in order and is shown from oldest to newest episode (based on publication date).
Is this set correctly? Then you can ask Spotify to change it for you. You do this easily by emailing podcaster-support@spotify.com. And rest assured, Spotify responds quickly ;-)
Should you still experience problems, please contact support.
