We are using TFS with the work item types of Feature for a while. The User Stories are all linked to the Features with the link type of parent (or User Story to Feature as child). I guess this is also used by Urban Turtle in the Product Backlog and the Sprint Backlog views. In the Project managment board however it seems that the link type must be "related" to see the user stories linked to the Features and to see the sum of the Story Points of its user stories.
Is this correct, or is something on our TFS not configured the way Urban Turtle expects it?
