I haven't heard of any new updates on the Win Live account linking issue lately.
What issues are you guys still experiencing?
This problem is showing up on the YS Center website and the Android app again. No Xbox information is coming through: no gamertags, gamer pics, or friends. So the leaderboard has no player names on it. All calorie information it working as far as I can tell. I don't know if this is effecting goals, challenges or events though.
