I just started my own Lemmy instance, and it looks to be mostly working.

The problem that I have is that the communities I went through the process of subscribing to only display up to 50 threads and no comments.

This looks like something I've seen on other servers, so I'm wondering what could be causing it and how to fix it.

ChatGPT says something about webfinger and nodeinfo, but I honestly have no idea what any of that is and there's no mention of it in https://join-lemmy.org/docs/administration/federation_getting_started.html
