Generally speaking, if it’s the first time you’re selling a product or you have a fairly recent account with no history then you are more likely to be marked for review before it is eligible to be indexed (There are many other factors as well, we do not share an exhaustive list). As you build reputation on our platform it should no longer be an issue going forward.
As a reminder, indexing on our search and browse pages is something additional we provide to allow people to discover your page. It is separate than publishing your game. You are in control of publishing your page, as soon as you publish it it is fully accessible and public.
Hope that helps
