Comment chains not appearing.

Hey mlem folx! I’m using mlem on iOS.

I’m noticing that comment chains don’t always show up in the app. This happens one of two ways, from what I can tell:

1. the top level comment appears as normal, and there is an icon for however many replies, but none of them appear unless I share and open it with a browser; or,
2. I become eventually unable to see comments in comment chains, even if it’s a thread I am participating in.

I don’t know if this is a known thing or not, I admit I didn’t do too much looking through the history here. I hope it’s not a repost.
