The share address returns page 404 (even when the link is exactly the same as the one I have that the app is on).

Being on the chat page, then going to 'Google' or another source and then trying to go back (clicking back) returns error when landing on the exact same url.

Nobody else can join the chat. I believe this is due to language updates. Working on figuring it out.

I am trying to use the code as a base for a similar app, however, I encounter an issue that when I use the AuthService from another Service class,

this.auth.getUser always return null

ClassRoomService class

  async create(title, text) {
    console.log(title, text);
    const user = await this.auth.getUser();

    if (user) {
      console.log(user);
      console.log(user.id);
    }
    else {
      console.log("user is null")
    }
}

I wonder what is wrong with the code, would you be kind to give me some advice ?

Forgot to mention, I add a new function for anonymousLogin in AuthService

  anonymousLogin() {

    return this.afAuth.auth.signInAnonymously()
          .then(() => console.log("successful login"))
          .catch(error => console.log(error));
  }

In component script

		this.authService.anonymousLogin().then(() => {
			 console.log("in anonymousLogin");
			this.classRoomService.create(this.act_title, this.act_text);  --> the "async create function"
