I'm finally downloading the PS4 update now.. six and a half hours after servers have already gone up. I was continuing to try and find reasons why it wouldn't work and tried one more time before searching on here. Then, lo and behold, I didn't try anything drastic yet, and for whatever reason the launcher decided to download the latest build of May 31st. I have absolutely no idea why it just randomly started working but I'm still irritated over the ordeal.

Come on, SE. This kind of thing shouldn't happen. If you want PS4 players to be able to complete on a level playing field with PC users, you need to make sure we're on more equal footing. I don't know if this has to do with the fact that I'm a PS3->PS4 holdover, but issues like these are very bad, especially on patch days.
