RM 1.1 Clicking Download link on iPhone (6) results in gray screen

[jauburn]

When I click the Download link from the iPHone 6 to download a PDF, I should see the link to open the PDF in ibooks, but instead nothing but a gray screen is displayed in Safari. I can click the "switch windows" icon in the lower right and see the ibook link, but I can't actually see it or click it when the page is in full screen.

Can someone check this out and confirm or deny?

Thanks.
