Kbin magazine threads do not federate until interacted with.
codeberg.org
Scenario: a magazine "M" is hosted on kbin. User "A" on an external instance (specifically Lemmy, I'm unsure if this also happens when this external user is also on kbin) posts a thread to magazine M. User "B" on a different external instance cannot see user A's new thread. I have encountered this twice today, once on Fedia posting from feddit.uk, cannot see from my usual Lemmy account at rabbitea.rs. Second time posting from my account at rabbitea.rs to kbin.social, cannot see my thread on feddit.uk See screenshots of this latter example - my thread is the one about this particular issue.

I did some further testing of federation issues, and have discovered that Kbin (at least Fedia) magazine articles don’t federate to remote instances unless they are interacted with on the host instance.

YSK: If you own a magazine on Kbin, make a point of interacting with everything (just an upvote is fine) to ensure it gets pushed out and seen, at least until this is fixed.

(that includes this article, can’t see it from Lemmy until it gets interacted with on kbin.social!)
