As I know there is no way to easily and quickly scroll notes in notebook on Ipad. I have notebooks with over 1000 notes and it's very frustrating to wave with my hand every time I want to see notes from the bottom of the list.
You can see short line, but there is no way to use it.
And there is no such a problem on Android App.In previous version of IOS App not only I could scroll, but there was little info about date of notes on the scroll bar.
So please consider to resolve this issue somehow.
As far as I know the same problem is with scrolling notes inside.
