Cannot download games from the xbox games app due to age restriction

Have exactly same issue. Couldn't fix it in XBox app, but there's a workaround - install same game from Windows Store. Once you start installation from Store app, it shows up in XBox app and all works fine. Your mileage may vary, but worth a try imho.

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 despite this Roy

Exists the possibility that this could be a temporary issue, right now there isn't a similar outage reported

But I'm seeing some players posting similar threads in the forums.
Please try waiting couple hours to see if the status page acknowledge the problem (you can start to report this as well using the web page)

Also, please keep an eye on the Xbox support Twitter page

what is you age on your profile, some of my kids cannot play certain ea games due to age restrictions for online.

Hi, as that game is published by EA it may be their age restriction policy that is the issue. I believe their policy prohibits anyone under 13 years of age from playing EA games online.

EA base the age on the birthdate that was set when the Xbox account was created and that cannot be changed.

This is due to a age restriction on the profile called 'Family Settings'. You have been restricted to play games of a certain age category, therefore you are unable to play online.
