i just got the game yesterday and it worked fine but when i logged on three hours ago it started saying that i need to sign into playstation network ive done everything i can from deleting the game and all data to restarting the ps4 and router. ive also signed in and out of my ps4 when i try to log in to my freinds game it doesnt work and i cant have them join me but i can play offline which isnt what i want to do at all i want to be able to play with others otherwise its a waste of 20 dollars. ive talked to a few of my freinds and it turns out im not the only one its happening to and i know its not my account because other games work fine that also need playstation network.
