I've uploaded an update of my game today (New project post). It's been a few hours already but the game isn't on the latest section.
This hasn't happened with my other game. It got into the latest section as soon as I made it public.
As of today, there are many projects competing for space in the “Latest” sort option on the browse pages. Generally speaking, we don’t recommend you rely on that particular page for the promotion of your game. It’s not that high-traffic and there is limited space for the hundreds of projects that show up daily.
Although writing an update for your post can contribute to how your page will be refreshed on the latest listing, we can not make any guarantees about how that will happen, as there are many factors that contribute to how your page is displayed on our browse pages. We recommend you continue to write posts and share what you’re making with your own audience so you can help grow your page organically, as that can be a good way to help our algorithms spot your page.
Hope that makes sense
