SwiftUI watchOS 7 Multi-page App Can't Swipe Issue

Hello,

I have a watchOS 7 app that has multiple pages. It's is built using Xcode 12 Beta 2 as a SwiftUI App and uses a TabView to define each page of the app. When I run the app in the simulator I can swipe right to left to move from the first page to the second. Once on the second page however I swiping from to left to right doesn't move back to the first page. Nothing happens. The interface remains stuck on the second page. I am pretty sure this used to work in Xcode Beta 1. I don't have an actual watch device running watchOS 7 to see if this is a simulator only issues. Here's the code that sets up the main App structure for reference.

Code Block 
@main
struct MyApp: App {
    @StateObject private var model = Model()
    @SceneBuilder var body: some Scene {
        WindowGroup {
            TabView {
                PageOneContentView().environmentObject(settingsModel)
                    .tabItem {
                        Image(systemName: "1.square.fill")
                        Text("First")
                    }
                PageTwoContentView(model: model)
                    .tabItem {
                        Image(systemName: "2.square.fill")
                        Text("Second")
                    }
            }
        }
        WKNotificationScene(controller: NotificationController.self, category: "myCategory")
    }
}
