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?
There is something else going on with replication of comments and postings to other instances. When I look at your home instance, I only see 2 of the 5 comments on the posting you are reading. https://lemmy.world/post/103943
This comment is now comment number 6. EDITED to fix link to lemmy .world
