Enabling the Teams feature changes your Stories view and enables new functionality. In this article, you will learn how to use the Stories view with Teams.
Once you enable Teams, you will find a Team switcher on the upper right hand of your Stories page. You can use that to select the Team board that you wish to view.
In addition to the Team board changing, you will also see that Team's Projects and Workflow States.
Epics can be filtered down to just the Projects on that board by hovering over the Epics menu and selecting "..." and then pressing "Only Epics from Selected Projects".
