3D FlipBook - Adding hyperlinks in Adobe Acrobat Pro isn't working in 3D FlipBook Pro

Just purchased the Pro version of 3D Flipbook. I'm currently assisting with a new PDF newspaper site that has hyperlinks added to the PDF using Adobe Acrobat Pro. When I save the PDF and upload to the Wordpress site, and swap to the new shortcode, I open the PDF but the pages that had hyperlinks are acting like nothing is there. I tried editing the 3D Flipbook settings for this PDF and set all pages to interactive, but it doesn't help. What else am I missing?
