Angular Auth0 after login secured auth guard page doesn't show after redirect - auth0

Question

I am testing Auth0 with angular for the first time and have run into an issue. I let my user login trough Auth0 and after they have logged in I redirect them to my dashboard page that is protected with Auth0 guard. I have managed to redirect the user but after they log in the URL shows that the user is on the dashboard route however they can't see the actual dashboard content. I tried to see what is going on and I think the problem is that the user is logged in but the auth guard boolean is never set to true which makes my program continuously refresh the URL. When I take the auth guard off the route the redirect works and shows the content. I have played around with the code hoping to figure it out but so far no luck.
I will share my code if I have to share more code please let me know.
app.module.ts
const appRoutes: Routes = [
{ path: 'app-dashboard', component: DashboardComponent,
canActivate: [AuthGuard]
},
{ path: 'login', component: LoginComponent },
{ path: 'app-shell-start', component: ShellStartComponent },
{
path: '',
redirectTo: '/app-shell-start',
pathMatch: 'full'
},
];
auth.guard.ts
#Injectable({
providedIn: 'root'
})
export class AuthGuard implements CanActivate {
constructor(private auth: AuthService, public router:Router) {}
canActivate(
next: ActivatedRouteSnapshot,
state: RouterStateSnapshot
): Observable<boolean> | Promise<boolean|UrlTree> | boolean {
console.log("start")
return this.auth.isAuthenticated$.pipe(
tap(loggedIn => {

if (!loggedIn) {
this.auth.login(state.url);
