I've added a .toolbar to the top level of a NavigationView that will eventually be used to select items in a list without using swipe gestures (up button, down button, etc.). I also have a .navigationBar going on, to access other views for Account and Settings.
For the most part it's looking really good, but when I follow a NavigationLink (in .navigationBarItems) within NavigationView, and then use the built-in back navigation, my .toolbar disappears from the top level.
Am I putting the .toolbar in the wrong place? It feels like a problem with .navigationViewStyle(StackNavigationViewStyle()) because when I comment that out, the toolbar will not disappear upon navigation... but I don't like how the default behavior works in landscape so I'm relying on it.
