Error linking account

Hi, I'm following [this tutorial](https://firebase.google.com/codelabs/build-android-app-with-firebase-compose#2) and when I reach the Firebase Authentication step, I get the following snackbar error while trying to create an account:

> The given sign-in provider is disabled for this Firebase project. Enable it in the Firebase console, under the sign-in method tab of the Auth section [ Please verify the new email before changing email. ]

However, in the Firebase Console I've already added the access provider for email/password (and the anonymous, which is added by default), both have a green tick saying **correctly enabled**.

I've recreated the Firebase project and the local code, and reproduced the steps (there are very few steps) as straightforward as possible, but I still get this error.

Any ideas of why this could be happening?
