Auth works correctly in Firebase Web but Analytics does not work

The code below uses Auth and Analytics. Auth successfully generates anonymous accounts, but Analytics dashboard always show 0 for new users.
I referred to the official documentation.

    private firebaseConfig = {
      // ............
    };
    
    private app = initializeApp(this.firebaseConfig);
    public analytics = getAnalytics(this.app);
    public auth = getAuth(this.app);

    public async loginAnonymous() {
        await signInAnonymously(this.auth)
        .then(() => {
        })
        .catch((error) => {
            console.log(error);
        });
    }

Some answers on StackOverflow say that it will be reflected in a few days, but I have been waiting for 3 days.
My understanding is that calling getAnalytics() counts as one user, is this correct? The dashboard doesn’t work no matter how long…
