I seem to be having this issue now too? I totally get internet propagation, but my post in Release Announcements isn't visible either. If I look at Community > General I can see that the last post was by me 56 minutes ago, but if I click into Release Announcements the actual post I made is not there at all. I reached out to support via email. I also checked from a different computer with same results.
Sometimes the first page of a category behaves a little oddly. You didn't have to. The post was probably fine. As for your game, it's newly created, and it has a price tag, so an admin has to look at it first. If you had started another topic instead of hijacking this one, like we ask everyone to do, you'd have seen the rules of this category pointing you at the Getting Indexed on Search & Browse FAQ where all this is explained. Please wait.
