The Push Notification Activations page displays real-time activation status of push notifications that a user subscribes. You can view activation status, last notification time, and status information per user or device. You can deactivate push notification subscriptions when:
A user experiences notification problems.
An existing activation is invalid.
Maintenance or upgrade activities are scheduled.
You can expand each row to see details such as VOIP and non-VOIP device token(s), and SIP Instance ID, which help debug push notification issues associated with a user or device.
