I was testing out my PS4 on Christmas with Knack, when i tried to view my trophies it wouldn't show me any unless i was online.
I remember this happening with the PS3 when they changed how Trophies worked and i had to switch them from Online Mode to Offline Mode to view them without a net connection. i also know that on my PSVita i could view my PS3 Trophies as well but only in Online Mode so i'm assuming the PS4 is using a similar system to what the Vita used for trophies since you can view PS3 and Vita Trophies as well.
Thing is, it was ages ago i did the mode switch on my PS3 and the Vita it's like a separate tab at the top which doesn't work if your not online. i can't remember what setting i had to alter on my PS3 and i can't seem to find anything option like that on the PS4.
So i am wondering How can i switch PS4 Trophies to Offline Mode?
