Both commands: .onDisappear(perform: ) & .onAppear(perform: )

are bugging the NavigationView (.navigationBarTitle) feature:

    .navigationBarTitle("Opciones", displayMode: .inline)

When used the navigationBarTitle is removed or not working in the View where you use invoke it. This happens using BOTH: .onDisappear(perform: ) .onAppear(perform: )
