为什么旧的 Email 在 firebase 和 VUE.JS 更新后返回？

Question

am trying to allow users to change their primary email in my VUE App which uses firebase as authentication,

the code am using works fine and it gives me that the email has been updated, however after the email is updated I can log with the new email for one time only and once I have logged out then like it has never been changed, and the old email is working again.

What is am doing wrong that keeps getting the old email assigned with the user

currently am using the following code:

firebase.auth()
.signInWithEmailAndPassword(oldEmailAddress, currentPass)
.then(
    () => {
        firebase.auth().currentUser.updateEmail(newEmailAddress).then(() => {
            console.log('Email Updated');
        }).catch((error) => {
            console.log('Email Error updating user:', error);
        });
    },
    (err) => {
        console.log('log in user error:', err);
    }
);

Answer 1

try using this function from firebase/auth as the docs say:

const auth = getAuth();
updateEmail(auth.currentUser, "user@example.com").then((result) = { console.log(result) })
