I recently upgraded our Phabricator instance (https://reviews.llvm.org), and some existing users are getting "Primary Email Unverified" warning. However, users could not find the way/button to verify the primary email. Note that in the screenshot, there are "Verify" buttons for secondary emails but not the primary email.
