Nope, soft reset didn't help at all.
All my accounts ( microsoft, xbox and nokia) were set at US, but I don' think thats relevant, cause the settings are missing, not some features.
By logging in xbox, did you mean settings > games > connect with xbox?
If yes, then I had logged in.
Also, there's my avatar in xbox games app, therefore I think I've logged in.
Guys, been having this problem since I got my black 920 a few days ago, it had portico preinstalled.
Whereas my friend's 920 without portico had no problem whatsoever.
Could it be that portico is the culprit?
