Has anyone been able to use NavigationSplitView in tvOS? I tried building something dead-simple like the example on https://developer.apple.com/documentation/swiftui/navigationsplitview and it just doesn't work on tvOS. It shows the list of entries, but none of them seem to highlight (although I can hear sounds as if the focus is changing), and clicking the button to select them does nothing. If I start with a default selection, it starts by showing the detail, and the menu button will take me to the list, but again focus appears and nothing can be selected (other than the bloop sounds that hint the focus is changing).
