Bad app after update

The app used to work perfect for me with its reading mode when I read novels. But it sucks after the update. I could not find the feature now. Although I could switch to the reading mode for sometimes, but not always. I got luck to switch into reading mode at one time. Then even the same page when the reading mode on, if I quit from this mode, refresh the page, I could not switch back. The green switch button could not show on the page no matter how I pulled the page up and down, or switch to the next page. Please help or I will give five stars.
