When trying to sign up with an email provider (that blocks some of our communication), the app will take you to a login screen if the email provider blocks some of our communication.

At sign up you just need to provide an email address that will cause our backend to respond:

Use a different email address. This email provider blocks some of our emails.

We've seen this happen with some @qq.com email addresses, but it can be tested easily with Mailinator as well.

Expected

The error message should be shown to the user instead of moving theh user to the login screen.

Steps to reproduce the behavior

Sign up using a mailinator email address.
