I'm having same problem many other people are having. First started about 2 weeks ago when i couldn't sign in to xbox from my pc but i could still play daily challenges. Error message said i wasn't connected to internet but i was.I could sign in if i went to xbox.com but that was useless. Yesterday, i could no longer play daily challenges.I get the 002000 error code. I hadn't done anything different, I've made no changes. I have tried every fix that i can find online. The app troubleshooter tells me the display adapter might need updating but it is up-to-date. Totally frustrated. Has anyone found a fix for this?
