Hi, thanks for the reply. The content in question sits on a WP page at https://followtheboat.com/ytchan/
WordPress does not support easy RSS conversion of a page and what RSS it does try to create is not clean. Feed readers have problems dealing with it.
There are 'html page to RSS' converters out there and they work by identifying the CSS selectors, making them RSS placeholders instead. The problem they run into is not being able to differentiate between the same selector for the different feeds. For example, the CSS for the title will be the same CSS for every article, so unless it intelligently appends an increasing number (title1, title1 etc), it pulls the same title for every feed.
RSS.app, however, is one of the few services that can successfully pull apart this page and serve it up as a readable RSS feed. I just don't want to go with RSS.app!
I'd be interested in your thoughts, thanks.
