Can I change the email address on my account?

Your account email is the identifier you log in with, and it cannot be changed by you from the app — in Settings → Profile the email field is shown but locked (disabled). You can freely update your name and phone number there, but not the email. If you need your login email corrected or changed, contact support and we'll help. Keeping the email fixed is a deliberate security measure so that the login identity tied to your account and verification can't be altered without oversight.
