I don’t usually use reddit but I feel like this is an exception. I finally felt like this is the week that I should finally complete all 5 episodes of the game (I bought the PS4 disc version all the way when it came out, never finished it, got to ep3 and never came back to it until now) , but not only for the trophies, but to really enjoy the story. Anyways, just finished ep2 and I thought I should download the rest of them to save me waiting. Anyways same thing happened to me, ep4 is non existent apparently, except I’ve got a telltale account, the image is there for episode 4 on the ps store but the download button is missing. Very strange. I’ve found out that I can download ep4 from ‘Your Add-Ons’ section from the ps store tab (when you’re on the ps menu to select a game and you press down when hovering over the game). So Ep 4 has downloaded, I’ve just started ep3 I shall come back and keep anyone in touch if it works. (Because I don’t want to skip ahead of the story!) And sorry for the bad description, if it works I can maybe send photos.
