Yesterday I did some testing and documentation on how sharing works using Content Packs. In Short
1. I have a Group Workspace that contains a data set, reports and dashboard
2. I have added these objects into a content pack.
3. I have added user access to this content pack
When users connect to the content pack, they can copy the dataset, report and Dashboard and then create their own reports and dashboards
Yesterday, they were then able to share their dashboard with other users.
Today, there is a message saying "You do not have permission to share this dashboard".
I am almost 100% sure this is different behaviour than yesterday as I have screen shots showing different behaviour. So has somethign changed, or have I overlooked some setting that allows users of a content pack to share a copy of a dashboard?
