So I’ve hit this a couple times and I can’t figure out the intended UX.
I make a comment on a shared item. Later someone replies. Cool. I see the little badge and click, see “So-and-so has replied to your post” but when I click it, it opens up an empty/blank feed.
At first I assumed this was because I have things set to “Unread only”, but even changing that doesn’t make take me to the comment when I click on it.
I don’t know if this is intended to work this way, but clicking on comments and comment replies should definitely bring that shared item and comment chain into view, regardless of settings.
