Unfortunately it's now no longer working? It keeps taking passes. It may be because I'm reading classic stories, but I don't know how because it worked perfectly a few days ago.
If anyone has an issue where it doesn't work, I uninstalled it and reinstalled it and it saved all my progress and it worked again! So if you need to, just try that. It should save, like it saved for me. Just make sure to re download it from your download tab.
