Several PlayStation 4 users have gone to forums to report problems with new features offered by the new PlayStation 2.00 firmware update, most troublingly an issue restarting the console from its new "rest mode."

Sony has acknowledged the problems in a statement and through its official Twitter account but their number of users affected, and what is causing the problems, remains unknown.

Users in this thread on PlayStation's official forums say that they can't boot up their consoles once they enter "rest mode" — a renamed version of the PS4's "standby mode" — and that their PS4 controllers and buttons are unresponsive. The console's multicolored light flashes orange for them, indicating a problem.

Sony told Game Informer that it is "aware of issues reported by some PS4 users" following the firmware update, and that it is investigating. For those affected, PlayStation support has been advising users to restart the console in Safe Mode,and update its software from there.

A more persistent problem appears to be with sharing video clips to YouTube, a feature introduced with the 2.0 update. Users are reporting problems tied to connecting one's PlayStation to a YouTube or Google account, and then difficulty uploading videos to it.
