Reproduce the issue in the People sidebar by opening an unverified user with no logged-in devices, then trace the profile sidebar's loading state and verification information. Confirm the intended empty or unavailable state with the issue context, and consider the work done when the sidebar no longer spins indefinitely and communicates that verification cannot currently be performed.
