Hi, I have an issue with applying the .glassProminent modifier to a button placed in the leading section the nav bar that triggers a push navigation to another screen in iOS 26. I have made a simple sample project to verify it happens there too, and I'm getting the same behaviour where the prominent button "flashes" with a darker background and disappears. The HIG does mention not tinting or adding custom backgrounds to tool bar items in iOS 26, so I'm unsure if this is a bug in iOS 26 or the unexpected behaviour they refer to when adding custom tint/backgrounds. Below is the simplified sample app code: var body: some View { NavigationStack { VStack { Text("Main Screen") .font(.largeTitle) } .navigationTitle("Home") .navigationBarTitleDisplayMode(.inline) .toolbar { ToolbarItem(placement: .navigationBarLeading) { NavigationLink(destination: SecondScreen()) { Text("Push Nav") } .buttonStyle(.glassProminent) } } } } } struct SecondScreen: View { var body: some View { VStack { Text("Second Screen") .font(.largeTitle) } .navigationTitle("Settings") .navigationBarTitleDisplayMode(.inline) } }
