Server Error / in Application when attempting to purchase backwards compatible games in ...

Recently, I changed my Microsoft account from child to adult by un-adding then re-adding to the family as an adult account. I did this because I am over 18 but still wasn't allowed to purchase any backwards compatible games from the Xbox One Microsoft store.
Since then, any time I attempt to purchase a backwards compatible game, I get a pop up error message:





Once I encountered this issue, I attempted to purchase the game through the Microsoft store on my computer only to receive the same error message (This screenshot is from my computer but is identical to the one on my Xbox One). My friends have confirmed
for me that they do not have this issue when attempting to purchase games like this. I don't often purchase backwards compatible games and could have a friend purchase them for me through game share instead, but it is an inconvenience and I would like to have
the system operating properly instead of having to move around issues that shouldn't be there. Is there any way to help this?

Error with backwards compatibility

Whenever I go to backwards compatible game store and select "Get price" instead of it showing me the regular window I get an error page that says "Server error in "/" application." It only happens in console and only for backwards comparible 360 games, not
regular xbox one games. Any tips?

 

Server Error in '/' Application when trying to buy Backwards Compatible Games

Try clearing the cache of the browsers. For the console hold the power button on it for 10 seconds till it shuts down then unplug it and let it sit for 5 minutes.

 

have you tried signing out and back in after you changed the child to adult account?

 

This may help.
