Where: Email form: competing account and billing fields made the correct target ambiguous.
Why: After invalid input and back-navigation probing, the flow did not provide a clear recovery path back to a successful account email update.
Where: First-plausible path on /demo-app/account-settings: the persona saved after choosing the first reasonable-looking email field.
Why: The persona clicked the first plausible email field and save control, then stopped without inspecting alternatives or retrying after the vague result.
Where: Email form: competing account and billing fields made the correct target ambiguous.
Why: The Account email and Billing email labels were similar enough that this persona chose the wrong email field and never saw the required account-update confirmation.
Where: Mobile viewport: the primary save or submit action was not visible enough to complete.
Why: On a 390x844 viewport, the persona found the visible field but the save/update action was not an obvious touch target, so the account email change never reached confirmation.
