Ok, I think it may just be some syncing issues. I can see comments/reactions slowly start pouring in.
I recall a similar experience when using matrix chat for the first time. Everything is synchronizing very slowly for the first time creating very confusing experience for new users.
So I think what you're saying is that you've created a Lemmy instance and joined a community from another Lemmy instance but you can't see all the posts?
My understanding is that your instance will only start syncing content from that community AFTER someone on your instance joins it. If you're the first person on your instance to join cats then you won't see anything from before the moment you joined, but you will get all the content that is posted after you joined. If you aren't the first person on your instance to join then you'll be able to see older posts.
Oh I see, thanks. That's good to know. Content eventually started syncing in, but I had to subscribe to every one of the communities I found first.
Do you think that a search function may be integrated one day directly in the standard UI? Element-desktop for matrix offers searching for communities on other nodes (although only on selected instances).
