*Apple News on iOS and macOS no longer supports adding RSS or ATOM feeds from anywhere. Full-stop, period. It will immediately fetch, then reject those feeds and fail to display them, silently without any message or error. I can see in my own server’s log that they make the request using the correct app on iOS and macOS, but then ignore the feed completely; a validated, clean feed. They ONLY support their own, hand-picked, curated feeds now. You can visit a feed in Safari, and it will prompt you to open the feed in Apple News, then silently ignore that request, after fetching the full feed content from the remote site.
