Epik 1.4.1 only added the responsive/hamburger icon for the “Header Right” widget and Primary Nav location. It doesn’t have the code added for the secondary nav, but I saw Wes mentioned in another thread that he would add it for all of the navigation areas (including the Secondary nav) in the next update. Until then, you could add it yourself from this tutorial – http://ozzyrodriguez.com/tutorials/genesis/genesis-responsive-menu-2-0/
