Hi, I’m having some trouble with the SAFARI compatibility, is there something that i can do? the browser doesn’t show flipbook fullscreen mode.

and the other problem is: how can i PRE SET the landscape view mode on smartphone lightbox? i need to show on smartphone view, the PDF only in landscape view and not in portrait view.
