After a period of inactivity I recently updated to Indesign CC2017. In previous versions, through the DPS tools, I would be able to connect my device (an iPhone, iPad, etc.) and, preview my document through Adobe's 'Content Viewer' app. That no longer seems to be the case, is there an alternative? It was useful to have my device propped up and preview different changes regularly.
To use Folio Builder and Content Viewer, you have to use InDesign CC 2014. They are not available for CC 2015 or CC 2017.
You can still install CC 2014 concurrently with CC 2017.
What kind of format(s) are you wanting to produce?
