Hi, I posted my game SiNKR about 4 hours ago (12 EST, January 20) and it has not shown up in new releases and you can't yet buy the game
Showing up in new releases and having a purchasable page are different things. If you game wasn't purchasable then did you forget to provide payment details or publish it? If you have a paid game that can't be bought then the game will not be listed in the store (since it would be unavailable). It looks like your page is in working order now so I'm assuming you figured it out.
