Just started mine but it came up with an error message saying there's something wrong with the market place or something and it's still on 0% so I don't even know if mines actually downloading
Why lol? Seems to be working for me, sat there for ages waiting on a few % then i turned it off and 20mins later it's at 80%.
I'm so stupid. I looked every place on console settings apart from where it was. For future reference: System Settings > Console Settings > start up & shutdown > background downloads > enable. I must have disabled it at some point. Oh Aaron, you silly boy.
