SwiftUI bug with TabBars and switching them out for other views

ContentView.swift

import SwiftUI

struct ContentView: View {
	@State var loggedIn: Bool = false

	var body: some View {
		switch loggedIn {
		case false:
			Button("Login") {
				loggedIn = true
			}
		case true:
			TabView {
				NavigationView {
					Text("Home")
						.navigationBarTitle("Home")
						.onAppear {
							print("🍏🍏🍏🍏🍏🍏🍏🍏🍏🍏🍏🍏🍏🍏🍏🍏🍏🍏🍏🍏")
							print("Home on appear")
							print("🍏🍏🍏🍏🍏🍏🍏🍏🍏🍏🍏🍏🍏🍏🍏🍏🍏🍏🍏🍏")
						}
						.toolbar {
							ToolbarItem(placement: .navigationBarTrailing) {
								Button("Logout") {
									loggedIn = false
								}
							}
						}
				}
				.tabItem {
					Image(systemName: "house")
					Text("Home")
				}

				NavigationView {
					Text("Savings")
						.navigationBarTitle("Savings")
						.onAppear {
							print("🍏🍏🍏🍏🍏🍏🍏🍏🍏🍏🍏🍏🍏🍏🍏🍏🍏🍏🍏🍏")
							print("Savings tab on appear")
							print("🍏🍏🍏🍏🍏🍏🍏🍏🍏🍏🍏🍏🍏🍏🍏🍏🍏🍏🍏🍏")
						}
						.toolbar {
							ToolbarItem(placement: .navigationBarTrailing) {
								Button("Logout") {
									loggedIn = false
								}
							}
						}
				}
				.tabItem {
					Image(systemName: "dollarsign.circle")
					Text("Savings")
				}

				NavigationView {
					Text("Profile")
						.navigationBarTitle("Profile")
						.onAppear {
							print("🍏🍏🍏🍏🍏🍏🍏🍏🍏🍏🍏🍏🍏🍏🍏🍏🍏🍏🍏🍏")
							print("Profile tab on appear")
							print("🍏🍏🍏🍏🍏🍏🍏🍏🍏🍏🍏🍏🍏🍏🍏🍏🍏🍏🍏🍏")
						}
						.toolbar {
							ToolbarItem(placement: .navigationBarTrailing) {
								Button("Logout") {
									loggedIn = false
								}
							}
						}
				}
				.tabItem {
					Image(systemName: "person")
					Text("Profile")
