This could be happening with other instances but I’ve only seen it with lw. Occasionally I’ll make posts into lemmy.world communities that just don’t federate. It’s not delayed federation – the post always exists in that community but only on the copy of it here and only Lemmy.ca users can see it and interact with it. It’s kinda like a secret Canadian version of the community, I guess.

It’s more of an inconvenience because it happens fairly infrequently but is this a known problem? Is it resolvable?
