"Child account" WHAT THE ****????

Hi. My Xbox has been doing lots of stupid things lately. Really weird stuff but not problematic enough to start a thread about.

Today, however, things got pretty problematic. I was watching videos on the YouTube app and suddenly, the app kind of freezes. Only button that still works is the guide button. So I exit to dashboard. Then go back to the app. When it loads up, it comes up with some kind of "child account" BS. Says something like "child accounts can't use this app". WTF??? How the hell did my account turn into a..."child account" all of a sudden? I restarted my Xbox and it still gave me the same crap. Then I check all possible settings and nothing was wrong/nothing had changed. I can't use the app any longer. WTF is going on lol?

Same thing going on with me. Sometimes it works sometimes it locks me out and sometimes it talks about a child account.:?
Probably something to do with the free app weekend thing they got going on.
