@Chemlord11 Congratulations. I will now point out that instead of doing your reading of full volumes in the app, you should absolutely download every volume you purchase and read them there. They have final editing passes, better page breaks, colour illustrations, and sometimes entire bonus stories. The app is best used for prepub reading only.
No need to feel stupid though, the only reason such a question was obvious was the amount of times I've seen it before. It's surprisingly common.
