I can't see a lot posts / comments / replies on my lemmy.world account

I first noticed when I posted something and I could see that I've gotten a reply. But when I went to the post I couldn't see it. I use Jerboa and I got the notification that somebody replied so I could reply back to them over the message tab. However, I couldn't send it because the loading time took forever and eventually stopped with a "network error". Furthermore, when I go to a community I only see a fraction of the posts that are on it. When I switch to an alt account I can see the rest. Some communities don't show up at all. This even happens to posts and communities hosted on lemmy.world (like the case I talked about in the beginning) so it doesn't appear to be a federation issue. Does anyone have a solution to this?
