I want to add to this. I didnt have any bugs until the second to last day where for two of the choices. I read from the start to where the pay wall is multiple times. And they would not mark as collected. I tried reseting my phone, stopping the app, tried to spend the ten minutes reading the chapter backwards still nothing. The next morning tried again no results, thought when the day switched over to the last days comics it would finally give me but still nope. Well I got the badge.
