Context:

This issue occurs when a user enters their email with a formatting mistake, often an accidental space after the domain (e.g., after ".com"). This results in a failed login or registration attempt, even though the email appears correct at a glance. 

What to do:

Based on similar cases, this doesn’t appear to be an error with your email itself. Instead, we often find that formatting issues such as an accidental space after “.com” - can prevent the system from recognizing the email correctly.

Here’s what we recommend:

1. Double-check that your email is entered without any extra spaces before or after
2. Try typing your email address manually instead of pasting it or using the autofill feature, as autofill can sometimes insert hidden spaces or outdated information that may not be visible at first glance.
3. Once corrected, try logging in or registering again
