@ImpossibleUmbrella It's possibly you are tapping the very top iOS status bar area which is the global shortcut to scroll to the top in all apps. If that's indeed what's happening you can tap it again to return to your last read position (assuming you didn't manually scroll yet) or go to the behavior settings and turn that off for Ivory.
@ivory Ah yes. I have done that too. But as you say that’s undoable. It feels like I’m scrolling some how. Thanks for the reply! And it really is a great app (I tried loads and it’s easily my favourite).
