I own the limited edition physical release of Life is Strange and it says on the box that it includes developer's commentary.
There is a tab for it in the main menu, but when I select it, all I get is a message that "new download content is available" and I get redirected to the PSN store page. There, it shows the season pass and each episode available for purchase and no other available downloads. Since I already own the game, this is not helpful.
There was no code card in the box other than the Square Enix product registration code.
How do I gain access to the developer's commentary?
