So, this exact issue was occurring with me, but I did some experimenting. It only really happened with my most recent save at the time, which was saved on the "You've finished Kate's Story!" screen. Instead of clicking forward, as is habit, I instead chose to click the little "door" button on the bottom of the screen, taking me to the front door, where I then went back to the lobby. From then on, the game took over, and the updated version began playing as intended. I hope this solves your own issue.
