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.
I think it works for replies of comments… you need to copy the link from the federated icon next to the chain icon. That is the correct link that should be posted in the instance you want synced.
