podcast rejection

I can't really help you as this isn't a technical matter, but that of the actual content of your podcast. I listened to a few very brief clips of your top episode, and nothing suggested itself to me as objectionable. Apple list likely reasons for rejection here:

If you feel you are being treated unfairly you could try contacting Podcasts Support, but basically it's their decision. Go to https://itunespartner.apple.com/en/podcasts/overview and click the 'Contact Us' link at the bottom of the page.

Podcasts Connect says your feed is 'prepared for submission', meaning it's OK, and on a quick check it seems to be fine. Was it submitted and then rejected at a later stage? The only problem I can see is that your media files force a download when accessed in a browser, instead of playing within it as they should: this might be a problem and you should try to correct this.

You haven't answered my question. Was your feed rejected immediately upon submission or after a delay of a few days? Was there any error message?
