Was good and now very annoying. Why put zoom (word/line spacing will change) / adjust brightness on reading screen? Is extremely easy to trigger during navigation and mess up the whole reading view. Get messed up several time everyday, pls make a way to disable it in setting. Moreover, not everyone need sync, everytime on/off mobile data and switch app, there will be a moment of blackscreen/ hangging due to network timeout. Or have to restart the app to gain back the reading view.
