Help: federation issues with communities not updating.
I recently migrated from lemmy.ml to lemmy.world to help with decentralizing and server load. I've noticed that a community I moderate, c/worldbuilding@lemmy.ml, is not updating: one of the mods I added isn't showing up on the sidebar, and a mod I removed is showing up. Plus, if I visit my community from lemmy.ml instead of lemmy.world, I see posts that aren't showing up on lemmy.world.
I have also noticed that communities advertised in new communities don't also show up on other instances. This seems especially true of communities originating on lemmy.world (at least for me).
Each instance needs to be "taught" about a new remote community by a logged in user on the instance searching for the community. Community lists don't federate eagerly, it's a lazy/on-demand style of populating those lists. That's universally regarded as incredibly confusing, it's the current state of things.
I guess a way to force each server to federate with eachother would be to use accounts on both and cross search on each one?
It will fix itself eventually of course, but for now this is a weakness with a mix of large and small servers, empty and struggling servers, busy and quiet communities.
I'm subbed into a lot of communities that have content on their own instance but have not yet updated on mine, but a day after posting or commenting more start to appear in waves.
I literally just did the same thing. Started a community on lemmy.ml them I migrated to .world. I made my world account a mod, and from the .ml point of view it's all good. From the .world side I am still "Subscribe Pending" and it doesn't show .world in the sidebar as a mod.
I've experienced some lag and unreliability with content from lemmy.ml and lemmy.world. I guess they've grown a bit too fast. I imagine it'll stabilize later as the server owners catch up.
