kbin was designed or built with lemmy compatibility early on, and unfortunately not vice versa.
It's really up to the lemmy devs as to when they'll ever get around to it.
I just found the contrary. In a lemmy search field querying this thread (https://slrpnk.net/post/2450620) comes up empty every time (#Lemmy → Lemmy). Just to get here to respond, I had to search for the support community then browse for this thread. All in Lemmy.
Kbin cannot cross-post to anywhere.. not to another kbin or to lemmy. But I was able to search for a specific #Kbin thread in the lemmy search form, then search for another kbin magazine in lemmy, then use Lemmy to cross-post a kbin thread to another kbin instance.
Which ones aren’t working?
