I'd also like to mention that the slug changing to the proper url once title is chosen is not really happening for me either? I created the following article as a test, gave it a title, a small line of text in the article, and now, a day later, still has the id-like slug. As a Sage, this is a inconvenience, since I can change them, but if other people have this issue, that's going to be a problem for them.
Test article
(For context, this isn't the first time it's happened in my articles, it's been happening for at least half a month and in multiple worlds)
