Start by reproducing the issue through the displayed profile's contact information page in Chrome, editing the phone number, and submitting the existing number. Trace the profile edit and phone-verification flow from that entry point. Done means the duplicate-number case shows the intended alert and the page proceeds or redirects appropriately for verification.
