Im a bit confused. In a post (made on lemmy.ml) I replied to a comment (from someone on fmhy.ml) and my comment is not showing on sh.itjust.works. I am registered on lemmy.world As far as I understand these instances are connected. Is it taking a long time to aggregate ? Does it have anything to do with language selection? I have undetermined,greek and english selected. Here is the post but it is in greek so it may be a bit confusing.
So lemmy assumes there is no need to federate stuff to instances if nobody on those instances is subscibed to the community. Basically the users of the instance dictate what gets fedaterated to it. The partial existance of https://lemmy.ml/comment/760707 still is confusing to me though. If the parent got federated (meaning someone was subscibed before its creation) why not the replies? Maybe someone subscribed from sh.itjust.works and searched fot it?
The fact that children/replies to comments are not fetched seems like a bit of an oversight but it’s understandable since this would likely not be a big problem with users in the high hundereds.
