No, when a learner is transferred to a new Case Owner, the new Case Owner doesn’t then get access to previous system notifications. Previous notifications are visible for the previous case owner only from their account. This is both due to technical reasons, i.e., who the messages/notifications were originally sent to and to align with the current and existing privacy controls for messages.
FAQ: Regarding messaging in Console, can a new case owner see system notifications for a learner for the period during a previous case owner?
