Hi @bounce187 thanks for the message and for explaining the issue you’re seeing.
The root of the issue you’re experiencing is that the Seriously Simple Podcasting plugin uses an audio file URL in the feed that is actually the name of the post and does not by default link to the audio file directly. Instead, SSP passes the audio file URL request through an intermediate step where it logs a listening event for the Seriously Simple Stats plugin.
Because of this, even though you’ve updated the audio file on the post the audio file URL link you’re seeing on your site is still something like https://mysite.com/podcast-download/123/post-slug.mp3 – is that right? So because of this Spotify is not “seeing” that the underlying audio file has changed, because the audio file link in the feed is still the same, and in fact will always be the name of the post.
You are able to link directly to the audio files in your RSS feed if you’d like, but doing so would render the SS Stats module ineffective since it would be bypassing that listening collection step. The details of that change can be found in this gist: https://gist.github.com/TheCraigHewitt/e918e39c4432334fc59d4d99dd0f8cb4
Alternatively, you ought to be able to reach out to Spotify directly at https://podcasters.spotify.com/ and request for them to Refresh your RSS feed manually, which should pull in the latest files.
Hope that helps, and if there’s anything else we can do just let us know.
