Yes, I'm having the same problem (with a wrapped WKWebView, but presumably also the new WebView). The jumping-on-back-button issue was also a problem before iOS 26, but you could work around it by using .ignoresSafeArea(.all, edges: .bottom) However, now in iOS 26, Apple wants the content to flow behind the toolbar, meaning the above fix is no longer suitable. Did you manage to find a workaround?

Did anyone manage to solve this issue? Exactly as @jkmazur says: the title text is being rendered under the background color, and it's still broken in beta 9! Here's a minimal example: struct ContentView: View { @State private var path = NavigationPath() var body: some View { NavigationStack(path: $path) { List { Text("Item 1") Text("Item 2") Text("Item 3") } .navigationTitle("Title") .toolbarBackground(Color(red: 0.5, green: 0.5, blue: 0.5), for: .navigationBar) .toolbarBackgroundVisibility(.visible, for: .navigationBar) } } } Expected result: Title is rendered above the gray background. Actual result: Title is rendered below the gray background.

Can you show us your SchemaV1 and SchemaV2, and explain what you're trying to do? It looks to me like you're trying to manually create a SchemaV2.Month and a SchemaV2.Transaction in the willMigrate, which is probably not what you want.
