In a Sandbox environment that has just been upgraded to 2015 our System Administrators can see the new Hierarchy feature that allows you to visualise Accounts (and other entities) in context of their child records.
For all other test users this isn't available.
Am I missing a Security Privilege for others to be able to see this visualisation?
Note: This query is about the hierarchy functionality relating to data, not the internal Hierarchy Security feature relating to internal users.
