Hi there, unfortunately there is no setting to not collapse replies after a handful of comments. But, here's a little trick that users can do: With the new commenting, if you put a single space in the updates search, it'll expand all comment threads of the page you're on. Again, this isn't automatic, but it's an easy way to expand all collapsed threads on a page at the same time without having to expand threads individually : )
If this helped you, please mark correct to help others : )
