Content restrictions enabled on account out of nowhere?

Check if you have Family Settings enabled. Family Settings restrict use to these things: Parties, Downloading i.e Games/Downloadable Content. If you do not have Family Settings enabled, check if you are securely connected to the internet and are logged in
on a Xbox LIVE account.

Under settings Black ops has a content/emblem restriction. If enabled it keeps you from seeing such things. Check that first.

Hi Liam,

Thanks for reaching out to the forums! Are you the only account on the mentioned console. If their is a child account also on the console those child restrictions will also affect your account if that child account is currently logged in. If there are no additional accounts I would recommend verifying that your accounts "content restrictions" are set to the desired level to allow you to download the games and apps that you want. You can get here by navigating to Settings/Account/Content Restrictions .

Hi Adam!

Please go to https://family.microsoft.com/ and click on his account. Please check if screen time limit is enabled - try to disable it. In Content filters > Apps & games, try to select "Any age" or have you already selected that? Did you mean about that "Content restrictions - Apply age filters - allow all content"?

Although it is an account with no parental restrictions, "For parents are restricted" is displayed at Forza Horizon 4

Hi there,

please double check the birth date on the account to check if this is indeed a parent account and not a child account here: https://account.microsoft.com/profile/

also check if all settings for privacy and online safety are enabled at
http://account.xbox.com/settings like for example Allow user created content.
