Nonstop 90002 Error. Game unplayable. Why Won't SQUARE fix this?

I know this is allegedly a client error, but I refuse to believe this. When I first got the game on PS4 it worked flawlessly. Four days ago, when others reported the same thing happening, I started to get disconnects with the 90002 error whenever I'd leave a sanctuary. Retreating back to the sanctuary would briefly help, but since the servers went down for maintenance yesterday, now it just disconnects almost immediately with the error from the moment I spawn.

The odd thing is that I can play just fine on PC. I haven't had a DC yet on PC. I've seen that this happens to people constantly, but SQUARE refuses to even address the issue let alone fix it. I just got the game on PS4 a week ago, and as of now, it was a waste of 60 dollars (I got the game and expansion for PS4 but have had the game for a long time on PC). I can't even access Heavensward on PC unless I buy it AGAIN.

What can I do to fix this? Is there any solution at all?

yep same problem , I get 90002 every 10 minutes or so , my sub is up soon , so no more money from me ;/ was going to buy the expansion as well guess that's out ;/, strange I leveled from 1-31 without 1 90002 error .
