The Rally menu headings are no longer available individually but instead collapsed under a "Menu ⋁" dropdown
Release : SAAS
Component : AGILE CENTRAL
The new menu is more fluid in nature and when the user interface detects that there is not enough room to render the menu fully left to right, it will collapse it into a "Menu" dropdown.
In order to show the full menu again, widen the browser window or zoom out if the window has been zoomed in for readability.
