I've got a simple button within an indesign built article that is
linking to a PDF that is hosted online. When you tap the button It pulls
up the PDF correctly in the app, but when you try to pinch and zoom it
actually starts to zoom in on the app behind it, not the actual pdf.
It's a little hard to explain so I attached an image. You can see that
the PDF (that was filling the entire screen) moves off the screen as I
zoom in. Is this a bug or is this how it is supposed to act?
