Thank you. I was able to subscribe through your link, but before doing that I tried again and got the error: “This address does not point to an RSS feed or a website with an RSS feed”
This snip is from a few minutes ago, so you might be able to see it in your logs.
Strange. I wouldn’t expect this to be a problem on my side (all other author queries worked fine, you can check my feeds under the “AB HN” folder) but it was reproducible (tried several times when I set up the other feeds and today.)
In any case, this solves my issue for now, but let me know if you want me to try anything to help you debug.
