This is a continuation of the old post "Game jam not showing up". I don't care about the calendar but I can't even find it when explicitly searching for the jam. It's pretty much accessible only by link now. Edit: I did publish it, and it's not like I made it right now, it was around for a few days.

What can I do? Is it going to appear there after some time?

As explained in lots and lots of topics, your jam has to be seen by itch.io staff first, and not all of them are approved for the calendar. Not sure about search. If it takes too long, and you want to know for sure, the rules of this category tell you what to do.

(by the way, I didn't know that a cover was a requirement, so it might worth a read - if you want general public from itch.io to see your Game/Game Jam.
