can you please better explain your issue and how do you handle the two views?
The best way to handle them is to have two separated instances of the reader and handle them as you need (no shared parameters) .
We are using this two pdf views (Horizontal view below Vertical view) inside scroll view
1) When scrolling page external scroll view is getting activated hence not get page scroll
2) For that, solution we disable external scrollview on scroll page on PDFLayoutview then not getting control back to external scrollview
