withAnimation not working inside onReceive in the first trigger and works the next triggers

I'm trying to fix an animation that stop working with IOS 14 update and I traced the issue to a code similar to:

struct ContentView: View {
    var body: some View {
        VStack {
            Test()
            Test()
            Test()
        }
    }
}

struct ContentViewPreviews: PreviewProvider {
    static var previews: some View {
        ContentView().environmentObject(PublisherTest())
    }
}

class PublisherTest: ObservableObject {
    @Published var finished = Bool.random()
}

struct Test: View {
    @EnvironmentObject var publicador: PublisherTest
    @State var angle = Angle()
    var body: some View {
        Text("Test")
            .rotationEffect(angle)
            .onReceive(publicador.$finished) { in
                withAnimation(Animation.default.speed(0.1)) {
                    angle.degrees = 180
                }
            }
    }
}

I don't understand why the first Test() is rotated without animation and the others Test() are animated.

Thank very much for your advice.
