When Mail Settings asked Brevo for the account and Brevo refused the key, for example because this laptop's IP was not on the allow list, NGX treated that as a dead login and threw the member out of admin. Brevo is allowed to refuse the key. NGX is not allowed to log anyone out or take down admin for that. On the same Mail API Settings tab the API Key and SMTP Key rows now match the Ramblers Team Emails key row: a fully rounded secret field, a small gap, then View beside it.
