@Colarusso hope you don't mind me reaching out, but you seem pretty knowledgeable about RSS and I'm wondering if you can help me figure out if the RSS feeds for SCOTUS docket pages are broken or if I'm just doing something wrong when trying to subscribe? Copying the RSS link included on the page and adding that URL to Feedly pushes a link to the docket page, a link to it's XML page, and a link to it's JSON data but I've never gotten an update to a case.
@Colarusso sorry I meant to include an image to give you a sense of what I'm talking about in case you have no idea. Talking about the RSS links like in this example.

@NoelFrench well it's broken enough that it doesn't validate at https://validator.w3.org/feed/ or https://www.rssboard.org/rss-validator/

It seems like the issue is their GUID.¹ The isPermaLink attribute is True by default. So, the fact that they haven't defined that (left it blank so it's being read as True) means that readers are expecting a permalink (URL) not a date.

Whether or not this is the cause of your issue is an open question, but it is an issue on their side.

@Colarusso thank you for checking, explaining, and providing those resources! Super helpful. And also good to know that it's not me. I guess I will continue to send in requests to the SCOTUS webmaster to fix them.
