Firebase auth with email and password

Hi.

Implemented auth with email/password for firebase.
On local browser everything works as expected.
On iOS, when logging in, it seems that there is communication with the server, I am able to get bad password response if I am using incorrect password. When using correct password, get no response and the view stays on the login page, although it seems that the login was sucessful.

Any idea what is missing?

Thanks.
