Microsoft is rolling out a system update this week for Xbox One which covers a number of issues relating to SmartGlass, multiplayer, notifications, wireless, and dashboard performance some users are experiencing. Console owners who have their system in the standby "Instant On" mode will have already been through the process, while everyone else will be prompted to update after Thursday, December 12 at 2:00am Pacific.
Xbox Live's Major Nelson says there's plenty more where this came from next year based on feedback provided by the Xbox One community. A quick scroll to the comments section of the announcement blog and, yep, there's serious work to be done.
