A user can enable failure notifications for automations in their profile settings. Reference: Notifications
However, if the user is not the owner of an automation hosted in a shared space, they will not receive the expected notification.
Only the automation owner will be alerted.
This behaviour is different than the one for application reloads, where tenant admins and people with permissions on a shared space can also be notified.
Resolution
This is a current limitation.
