Re GETTING a pdf slideshow to advance (rather than to NOT advance),
what was missing for me in this discussion is that after you set the time withing Full-screen preferences, you then have to START your slideshow by selecting Full Screen from the View pull-down menu (or else the keyboard shortcut CTRL-L, as it says on the View menu).
I had exactly the same problem and solved it. Here's how I done it.
using Acrobat pro open your PDF
1) Go to left-hand side of layout and click the page tab.
2) Click on cogs to bring up a list and choose transition settings.
3) when this appear UN-CHECK auto flip.
4) Save file
and jobs done.
Hopefully this solves you issue or that of anyone reading it later on down the line.
