I have an indesign file that is 2048 x 6000 px. When I export for article, it goes through the motions as normal and then the export dialogues go away. However, an article doesn't show up in my chosen location, or any. No errors.
I figured this out and for anyone else exporting long smooth scrolling articles for DPS 2015, upon export for DPS Article, enter the width and hight of your target device in the dialogue box and check the Smooth Scrolling box. The mistake I was making was entering the document hight as apposed to the target device hight.
