Unable to log in - Code pin error

I think i've just found out a fix. You have to get in the game, click "Continue" and when you're in the black screen with the Apex logo, disconnect from internet. It will take some time but you'll get disconnect from code:net instead of code : pin. Once you get code:net, reconnect internet, click Continue again to get in the lobby. Now when you switch to Ranked, the game will freeze and you'll do the exact thing you did again, disconnect and reconnect, do the same with Arenas. Once you do this, exit the game and restart. I did this and the error was gone! If you still freeze in Rankeds or Arenas, don't disconnect and wait for the code:net error, then restart.
