Direct email notifications are sent to users who are assigned a pre-configured administrator role in an impacted Dynamics 365 or Power Platform environment, or Microsoft Dynamics 365 Lifecycle Services (LCS) project or environment.
My colleagues and I are Power Platform Administrators and Dynamics 365 Administrators, which I believe are pre-configured administrator roles, but none of us have been receiving notifications. I know there is a PowerShell command to set additional recipients to receive emails, but I believe this should be automatic for admin roles.
