No duplicate imports..still getting error

[puretext]

this.unregisterAuthObserver is not a function at e.componentWillUnmount (StyledFirebaseAuth.js:1)

Using Next.js and demo code:

import StyledFirebaseAuth from 'react-firebaseui/StyledFirebaseAuth'
import firebase from 'firebase'

@puretext there was a potential race condition in the case where the element was unmounted immediately after it was mounted. I just released v3.0.7 that fixes it. Can you see if it fixes your issue?

@nicolasgarnier it does. Thank You
