Non-default Firebase Functions region deployment location causes errors#

Issue:

You set CLOUD_FUNCTIONS_LOCATION variable which is responsible for a Firebase Cloud Function deployment region other than the default us-central1. The client-side Firebase Functions call is not updated accordingly.

Please update the Firebase Functions call accordingly. For more information, see Firebase Functions regions.

Unable to login with email + password#

Issue:

You are unable to login with email + password, but other authentication methods work fine.

Solution:

Disable Email Enumeration protection. If you are going to use FirebaseUI for authentication screens in iOS, Android or Web , you need to disable Email Enumeration protection. Otherwise, the FirebaseUI will not work correctly until Google resolve this GitHub issue. In our example apps, we use FirebaseUI for authentication.
