Started last week after almost a year with no issues, Lag spikes that made the game unplayable eventually ending in error 90006 and 90002, tried every online Square Enix provided solution, changed the router (although everything else was working just fine except this game), me and the wife having the same issue, so after all recommended workarounds, the issue still remains, hoping a future patch will fix this, because for us the game is unplayable now.
