Podcast Feed Not Showing Up

Your podcast appears to have been removed from the Store. As it can be subscribed to manually in iTunes there appears to be no technical problem. Other reasons for removal include unacceptable content, strong or sexual language in content when the 'explicit' tag is not set to 'yes' or in the title or descriptions in any event, and breach of copyright. I only listened briefly to bits of your top episode, and it seems unlikely that the first two are the issue; possibly the brief piece of music at the start has triggered concerns about copyright - if this is taken from a commercial recording then that's a breach of copyright and could get you removed. Obviously I can't know for certain what the cause is. You should have received an email from them if your podcast was removed, though it wouldn't have specified the reason; check it hasn't been spam-trapped.

You could try emailing Support at podcasts 'at' apple.com and asking them what is going on, but you may not get a helpful answer.

That will be your only option, but you will probably fall over a bug which will tell you the feed has already been submitted: the workaround is to change the title slightly.

I went to the Store URL you gave. It said that it was not available in the UK Store but was available in the Belgian Store, however in my experience when it says that sort of thing (usually it's the US Store) there's no point in changing countries as it always turns out not to be available there either.

I'm glad to hear you had a good result from them.

Your image is compliant with the requirements; it can take some days for an image to appear in the Store so it's probably just a question of waiting.
