Orchestrator Sending Notifications email on Error / Fatal to different orchestrator user accounts

Hi all,

I have been trying to set up Emails notifications once a Log comes in with Error / Fatal Level.
I have followed the instructions online:

I have setup the Server where the Orchestrator is running to Alerts.Email.Enabled = True

Reading further on the documentation there seem to be a few links down

I have assigned roles, View, Edit, Delete for Notifications on users accounts on the orchestrator.

Would anyone point me what is missing and why I cant get emails when a log with Error / Fatal Level comes in please
