Fedia Discussions

While there have been obvious problems with posts leaving/arriving on fedia.io I haven't bothered to ask but it seems slightly more reliable for posts from outside to arrive on fedia.io so maybe it's time to ask.
I haven't seen a fedia.io sourced post make it to my accounts on ohai.social, misskey.io or calckey.social so I'm wondering if that direction has a blockage or configuration error? They sometimes make it to lemmy.world but I'm trying to read the magazine there rather than relying on a hashtag that I follow.
