The comments section under any article now collapses when you click the thumbs up. Then it just shows "xx reactions on" and no comments. When you click on that it does nothing. You have to refresh the page, scroll down, and click on the "xx reactions" again to see the comments. Any clicks on the thumbs up or down may collapse it and require a page refresh.
Also, now that there are more articles when you scroll down instead of hitting the bottom of the page, the pop-out window to look at my own comments is obscured by the headline from the following article.
When I look at my comments, it's very hard to get any context of what they were in response to. I can't get a link that just goes straight to my comment in context where I posted them.
Get your **** together Yahoo. You've sucked hard for at least the last decade with all your "improvements".
