Overwatch not working? (Xbox One)

Is Overwatch not working for anyone else? It's been completely non-functional for the past few days now for me. When I log on to it from the website, the usual button to access it is gone. I can still get to the Overwatch page by clicking playlists and following the links there, but nothing comes up. It's basically just the map, none of the missions or anything load. I don't get any of the overwatch events in-game anymore either. It's a bit frustrating because there are some liveries that can only be unlocked through Overwatch. Any information would be much appreciated.
