As you can be part of multiple organizations at once, switching between them might be handy. The default setting is always that content from all organizations is displayed simultaneously.
However, if you simply want to view the folders and dashboards of a specific organization, click the purple organization icon in the navigation panel on the left-hand side of your screen. It is located directly above your profile icon.
After having clicked "All Organizations" you will now be led to an overview of the organizations you are part of. From this menu, you can choose the desired organization you want to switch to.
Which organization you are currently viewing will become visible within the navigation panel. If you want to switch to another one or back to viewing all organizations click the icon again to get back to the Organization menu.
