The Jira mobile apps for Android and iOS can already display JPD-Issues/Ideas quite ok-ish, but some things are still missing.
In particular, the Delivery and Insights tabs aren't available.
And of course, there are no "mobile" Views (lists, boards, charts), yet.
I can't say yet if and how I would want to work mobile with JPD. Adding insights would probably one of my typical tasks, though.
Out of curiosity: What plans/ideas/visions does the Atlassian team have for mobile working with JPD?
