yeah, the above is likely the issue. If there’s a community with 0 subscribers on on this instance, then none of the content will sync. As soon as there is at least one subscriber here, all new stuff will begin to sync, but it will never sync the history over unless you explicitly search it out as mentioned below. This is how Lemmy is designed to work, and i assume the reason is because syncing a huge back-catalogue could be very problematic from a resources perspective.
