Ok, my problem was it simply wouldn't download on my mobile browser because of size. It was giving me a message but I wasn't seeing it. So I downloaded to my PC and it worked fine, Table of Contents worked too. So I copied it to my tablet and it opens fine but I'm not getting the Table of Contents. I downloaded Google pdf Viewer but that was the same. It's a Samsung Galaxy Tablet 3 7.0. Yeah, kinda old but does anyone know a good app I can grab that will make the Table of Contents work?
