One of my gripes with the game (or I should say PS4's update system), was that when there was an update to the game, the game specifically told me to connect to the internet although I was, it couldn't find the update on time, locked me out of the multi but didn't tell me why (so I couldn't know what the issue was). It took quite a while to figure what the problem was, but there was nothing specific I could do (like manually telling PS4 to look for an update for the game.) I just waited, turned PS4 on and off again until it found an update for the game.
Usually I have things auto-downloaded but I was away from home so did a complete power down, and I had this update problem giving me trouble without description.
I hope they come up with a sturdier update mechanism.
