Anchor RSS FEED

I still can't subscribe in Apple Podcasts, though your link does lead to a feed. The one thing which caught my eye is that description for the overall podcast contains emojis, as does one of the later episodes. I don't know if this is the cause of the issue but it's asking for trouble - did you add them recently: if so they might be rendering the feed unreadable. I would advise getting rid of them.

The latest episode plays on the web preview page but not when I got into Podcasts app 'Browse' (on a Mac). I tried to subscribe (which on a Mac reads the feed directly), but it said that 'the server or feed cannot be found'.

If the feed had gone unavailable the listing would still show because Podcasts /iTunes Store caches the feed: and so would play episodes provided their URL hadn't changed since the feed was cached. This doesn't explain why more episodes work in the web preview, which should be reading the same database.

I can't proceed any further unless you post the URL of the feed, as I asked you to do.

What do you mean by your second sentence? And what are the URLs of your your Apple Podcasts page and of your feed?
