Forum Post: Hierarchy visualization not working for Accounts

We are using Microsoft Dynamics CRM 2015 (7.1.1.4461). I am talking about the feature found here: http://www.powerobjects.com/2015/02/11/hierarchy-visualization-dynamics-crm-2015/ The hierarchy visualization works in the User entity. The button shows up in the User list view and in the form view. However, no buttons are available in the Account list view or form view. I have a dev environment where the visualization does work for Accounts. Everything seems to match regarding relationships and hierarchy settings in Customization between the two environments . Any idea on what might causes this?
