I really like a lot of the books and storylines, but having to wait hours to read a single chapter mostly ruins the experience. I prefer to binge these things and I can't do that if I have to wait 3 hours for a key. I and I'm sure most people would greatly appreciate if you could earn keys by watching ads or something, that would make things a lot better. Just a suggestion, idk, but I think this would really improve my opinion and experience with the app. Cheers!
