I created this stack question: (https://stackoverflow.com/questions/67400875/ipados-swiftui-sidebar-3-column-missing-sidebar-button-with-3-views-in-navi)

Can anyone give any assistance? I'm new to SwiftUI so I'm not sure if this is a legitimate bug - that I need to file a radar about, or if it's user error, or something that's unsupported right now.

EDIT: Here's the content of the stack post:

Here's the code for 3 columns:

struct MainNavigationView: View
{
    @State var screen: Screen? = .home

    var body: some View
    {
        NavigationView
        {
            List(0..<10)
            { i in
                Text("Row \(i)")

            }
            .listStyle(SidebarListStyle())


            Text("Second")
            Text("Third")
        }
        .navigationViewStyle(DoubleColumnNavigationViewStyle())
    }
}

However, when I launch this on iPad (14.5), then I see two columns ("Second" and "Third") with a back button on the 2nd column, when I touch that I get the "List" Column showing but NO Sidebar control.

However, if I comment out

Text("Third")

in the

NavigationView

then I see Columns 1 and 2 and I DO see the sidebar control.

How can I get all 3 columns showing WITH the sidebar control?
