Here’s a frustration that we just came across.
Let’s say you are about to create a DPS folio and the client has said “I ONLY want portrait. There’s no way I will ever need landscape. Never!” (That little voice in your head should be shouting at you, “Don’t believe him!” But we’ll continue.)
Here’s a little tip from our book. Since the release of DPS tools v21, you can select the version number of the viewer you want your folio to be compatible with. But how do you know the version of the viewer you’re using? The trick is the same for publications you’ve downloaded, or in the generic Adobe Content Viewer on your tablet: Open a publication. Tap once to display the navigation controls, then double-tap at the top on the publication name. The viewer version number will be displayed.
