Xbox Live is a hot mess right now. It's been acting funny for hours, leaving some downloaded content inaccessible, and Microsoft has yet to explain why.
A quick look at the Xbox network status page as of 7:50 p.m. ET on Monday shows ongoing issues or outright outages across almost all of the key services. The store is functionally unusable, with shopping, access to owned content and basic account features returning errors. Live TV and movies/TV is also not working, as are most "Xbox Live Core Services," which is all things relating to your account.
