I tried contacting Adobe customer support, but no one seems to know anything in India.
I'm building a DPS document. I want all of my articles to be pdfs because then I have the option to pinch and zoom (where as with a jpg you don't). I have both vertical and horizontal layouts built in the same indesign document. However, when I go to publish to the Folio Builder as a pdf there is nothing on my horizontal layouts when I view it on the ipad. But when I export as a jpg, I can view both vertical and horizontal layouts on my ipad.
