@Maya thanks. I see it. On a long article scrolling to the bottom is a bit painful. And if there are a lot of comments then scrolling to the bottom of the article but not past into the comments is a bit painful. But at least there is a solution. Thanks. 

3.12.19 also hangs for me

any update? any intention to fix this? if you intended to kill instablog readership you've succeeded.

As of a few weeks ago you used to be able to subscribe to any author's blog posts using a URL like this:
https://seekingalpha.com/author/paulo-santos/instablog.xml

However, they appear to all have stopped working. Was this intentional? How do you subscribe to an author's blog posts in a feed reader now?

I did check and the https://seekingalpha.com/author/paulo-santos.xml URL only contains articles not blog posts.
