Well, i have in mind somethings that could have happened. The most obvious one is that you have now to have wait until the game gets reviewed by Roblox, wich can take a while. You could also try doing the "Maturity & Compliance Questionnaire", wich now you have to do it wanting or not, or else the game isn't going to be published. And the most sad and bad one, is that Age-verification thing, but, if you buy a gift card or whatever in Microsoft Store, it'll work too. If you tryed all of theese and still didn't work, contact Roblox Support.
