Hi vanbee, is this your first game jam as a host?
If so, then it normally takes a while after your jam is 'published' for it to show up on the jam page.
Happened to me after hosting my first jam last year, I had to wait around ~48 hours for it to be visible.
I just made my third game jam public yesterday and it was visible after only an hour or so.
I am not sure if this is random or not, just my experience of it.
BTW I took a look at your jam page, I was interested but it's a team jam and I only work solo. I wish you luck with it nonetheless :)
