I don’t think the instance is the issue like the other comment is suggesting (although I don’t quite understand the specifics of how it works). I’m playing around with it myself right now
If I search site:sh.itjust.works Hello and set it to 24 hours, I do see posts. So timing should be ok too
Update: So I think what’s happening is that the post needs to go through a few stages when it’s on a different instance
