    Checkout the answer above. The lazy way or not very good approach will be

    vm.$forceUpdate();

    it is not good approach though. Read more in mentioned link.

    You'll want to use an onAuthStateChanged listener instead of the currentUser:

    mounted() {
      firebase.auth().onAuthStateChanged((user) => {
        if(user) {
          this.ingelogd = true;
        }
      });
    },
    

    The onAuthStateChanged listener gets called each time the sign-in state changes, which ensures your ingelogd always reflects this state.

    For more on this, see the first snippet in the Firebase documentation on getting the currently signed in user.
