m/dance was created very recently on kbin.social and has only a few posts. Still, if I search for its URL on lemmy.world it is visible and I can subscribe, though I can’t see any of the posts: https://lemmy.world/c/[email protected]

I recently created the community c/survey_polls on lemmy.world, but when I search for it on kbin.social it is not visible. I can see the cross-posts I made on c/general and c/newcommunities, and looking at my profile through kbin.social my first post to c/survey_polls also doesn’t seem to be visible.

My point is, what communities/posts are or aren’t visible across lemmy.world and kbin.social? Do posts from one website only appear on the other if the community already has subscribers? Or is there some sort of time threshold?

To add to this, when looking at the post through lemmy.world you see 1 comment, while on Kbin there are 3. I’m even more confused now.

    I think this is true for both platforms - instances don’t federate communities (start polling for updates) until one user searches for that community. It takes a second search (at least in v17 lemmy, might be fixed in v18) to get the community to start showing. In Lemmy I think when an instance starts federating a community it also pulls the latest 20 posts, but given your example I’m guessing that must not be true for lemmy pulling in kbin magazines (not sure which side isn’t doing it, I’d assume the kbin side since lemmy instances seem to be coming in with those 20 posts).

    Not sure if related but I’ve see this exact issue with my personal lemmy instance. Federation seems to be fine but to and from kbin.social seems half-broken. I can open the magazine and some have a single post but most are empty.

    I also noticed that any moderation doesn’t transfer between instances. I moderate @BestOf. I did remove one post for being irrelevant with the spirit of the community and it’s still there on Lemmy. I hope this is something that can be fixed.

    I’ve noticed some similarly weird synchronization issues when posting on [email protected]: some of my posts show up on the kbin side, but not on the canonical instance.

    (Also, yay for m/dance! Am creator and would love some other contributors!)
