I'm at work now, but I'm going to update my PS4 when I go home for lunch. But I did come across this bit of info:
"Specifically, users are flocking to messages boards to report that the notification system is now a jumbled mess, as opposed to being sorted into individual categories like before. As such, you now have to scroll down a huge list in order to find the notification you want, as opposed to having them neatly sorted out to facilitate ease of browsing."
Obviously, the more organized the better. But has this or anything else as been an issue with you?
