I can log in to xbox.com, and click on family center. Whenever I select an avatar and "View Reports", it jumps to the report screen with the animated "Loading data" icon, as if it's trying to gather the data..... and eventually responds with:
Sorry, we were unable to retrieve the activity data.
Please try again later.
This has been like this for MONTHS. These reports are the main reason I got the family pack. What gives?
