I have a dashboard with data from datasets which are connected via Direct Query and an Enterprise Gateway. I activeted the Q&A in the dataset settings and it is working fine for the dashboard.
The problem is, when I create a content pack with these dashboard, reports and datasets, the Q&A feature is not available in the dashboard which you get, when you add the content pack anymore. In the original Dashboard, which was used to create the content pack, it is still visibile.
I would say that is a bug or?
