"To do this, change a setting" not working

Hi and thanks for reaching Microsoft Xbox gamer's community. My name is Josef.
I'm an Independent Advisor and a Microsoft Xbox user like you.

Hope you're doing great today buddy

Your brother is in a family group or is him alone?

Is this happening only with among us or every multi-player game?

And please tell me which troubleshooting steps you have done so far to fix this, in that way I can advise you different things or how to proceed

Hey, I'm glad to hear that! At least you was able to solve it!

If you don't mind, how you solved it?

Thank you for replying back but I got in contact with xbox online support and they helped me figured it out. Appreciate all the help for those trying to help 💕

Never seen an issue like this before, something I recommend trying real quick might be to clear you system cache or try re downloading your profile. If neither of those things work. Try buying it through either the xbox store or xbox.com.

It could possibly just be an issue with the Minecraft menu, similar to how you cannot use the GTA Store tab in GTA Online, it just black screens.

Hope one of these things could help you!

I have this exact issue but with the avatar store. Everyone suggests that you may have a child account or your age may be underage on the account, so check that out if you haven't. But mine is definitely an adult account, my age is accurately 21 on my system,
and all my content settings are unblocked :/

If I find an answer, I'll let ya know.
