I subscribed to communities, but my Lemmy instance receives only a few posts, comments and votes. I can see linked instances, but whether or not they sync data feels hit or miss. I’m not quite sure if this is expected. Does Lemmy have a utility similar to the Matrix federation tester?
I don’t see all the comments yet on your home Instance either. https://lemmy.haigner.me/post/8
At lemmy.ml - the “owner” of this community, I am now creating the 5th comment (you are reading it).
