This is a fairly persistent issue that appears to be exclusive to Connect, and extremely annoying.
Any time a post accumulates very large numbers of comments (say, 300 or more), Connect will eventually just… stop loading additional comments. At first, scrolling down will load a few more top-level comments, but eventually it’ll just give up and act like there’s no more comments to load, even though there Connect has loaded less than 50 comments out of a 1,000+ comment megathread. Worse yet, if a user direct links to a comment on one of those megathreads, Connect will load a completely empty comment thread. This issue doesn’t occur on Voyager or Jerboa, nor on the web UI.
Welp, I spoke too soon. Happens on this post: https://lemm.ee/post/4849090
Curiously, it seems that if I constantly scroll down and keep immediately loading comments, it seems to work. But if I stop and actually read, once I reach the bottom it won’t load any more.
Side note, some feedback in the UI regarding what’s going on would be helpful–a little pop-up or loading icon when it loads more comments.
