For example, I’m on Lemmy.sdf.org and I joined the [email protected] community. But there are many missing articles and comments. If I browse directly on Lemmy.ml for the same article there ~90% of comments are missing.
https://lemmy.ml/post/1152794 has 26 comments https://lemmy.sdf.org/post/11232 has 0 comments
Scope out this comment thread and come back tomorrow, things will look less funky: https://lemmy.world/comment/22210
It’s unfortunate that the federation replication is most weird when you’re new, disoriented, and most susceptible to getting confused. But once you’ve been subbed for a day or two you’ll have all the same comments everyone else does. It would be cool if a bit more back-catalog of comments was fetched, but it’s early days and not everything is perfect.
