Ionic 4 Skip Start-Page when user is logged in

Hi all,

i have a app with a login-page.

If the user starts the app for the first time the login-page will be shown and the user has to login. If that was succesfull the app redirects the user to the menu-page (and this loads the tabs and so on).

Now, if the user closes the app or sends it to the background and reopens the app, the login-page is shown for a short period of time (less than 1 second) and it redirects again to the menu-page.

How can i prevent the login-page to be shown when the user is already logged in and the user is reopening the app? With ionic 3 that was no problem for me (using setRoot) but now with ionic 4 i face this problem (maybe because of the routes…?)

Here are some code snippets from my code:

app-routing.module.ts

const routes: Routes = [
  { path: '', redirectTo: 'login', pathMatch: 'full' },
  { path: 'login', loadChildren: './pages/login/loginPage.module#LoginPageModule' },
  { path: 'menu', canActivate: [AuthGuard], loadChildren: './pages/menu/menu.module#MenuPageModule' },
]

app.component.ts

 this.splashScreen.hide();
            this.authenticationService.authenticationState.subscribe(state => {
                if (state) {
                    this.navController.navigateRoot(['menu/tabs/dashboard']);
                } else {
                    this.navController.navigateRoot('login')
                }
            });

In my AuthGuard i simply check if the user is logged in and return true or false. I followed this tutorial: https://devdactic.com/ionic-4-login-angular/

What do i have to do?
