When a Mist subscription expires, the devices associated with that subscription continue to operate normally, ensuring there is no immediate disruption to network operations. However, management capabilities through the Mist management GUI are restricted. This means that while the devices remain functional, you cannot make configuration changes, monitor, or manage them using the Mist management interface until the subscription is renewed. This restriction emphasizes the importance of maintaining active subscriptions for full access to Mist's management features.

Identify the Problem: Alerts are being generated and visible in the Mist GUI, but only some administrators receive the alert emails.
Possible Issues:
User email addresses not correctly formatted.
Email server blocking Mist emails.
Insufficient alert subscriptions.
Administrators not enabling email notifications.
Root Cause:
Since some administrators receive the alerts, email formatting and server blocking issues can be ruled out.
If alert subscriptions were insufficient, no administrators would receive the alerts.
The most likely cause is that the affected administrators have not enabled email notifications in their Mist My Account settings.
Resolution:
Ensure that all administrators have enabled email notifications in their Mist My Account settings.
