Oof. This definitely needs to get sorted out asap. It would be the death of a federated platform centered around discussion. It's kinda one of the main tasks.
Man if you look at this thread on Kbin and then again via another instance like Fedia, there are number of comments not federating across both instances. Kbin counts 24 comments and Fedia just 19. The missing comments on Fedia seem to be Kbin users. There's some comments in here that are upwards of 8 hours old that have not made it to both instances. This is really problematic.
Yeah the comments are not federating across fedia/kbin. I'm only seeing your comments on this thread when you've posted them on the server I am currently viewing. Even 8 hours after you commented.
I'm a big fan of Kbin but the project is a total mess right now and kbin.social is always down or only partially working. And there's next to no communication about what's happening.
I don't wanna do it but it might be time to pull up stakes and figure something else out.
