After updating a customer to latest, the customer reported losing the customized email templates for the blocked (now silenced) user.
In order to fix this, we had to run
update translation_overrides set translation_key = 'system_messages.silenced_by_staff.subject_template' where translation_key = 'system_messages.blocked_by_staff.subject_template'; update translation_overrides set translation_key = 'system_messages.silenced_by_staff.text_body_template' where translation_key = 'system_messages.blocked_by_staff.text_body_template';
Maybe it’s handy to add this as a migration? (first check if there is no existing silenced_by key already)
