``` ### If it still says "Initializing..." or shows an error: 1. **Check Firebase:** Go to your [Firebase Console](https://console.firebase.google.com/project/personal-operating-syste-37032/authentication/providers). 2. **Ensure "Anonymous" is Enabled:** Look for "Anonymous" in the list of sign-in providers and make sure the switch is set to **Enabled**. 3. **If it shows an error on the screen:** Read that error carefully! It will likely tell you `auth/operation-not-allowed` (which means you forgot to toggle the switch in step 2). Try this "clean" version. If it loads, we know the authentication is fixed, and I can provide the full notebook/time-tracker code for you to paste back in.
