Notifications takes a lot of time to load in Notification Client or Application

Description: Sometimes, when you try to send or receive notifications, you may experience slow performance of the Notification Service.

Resolution: This issue occurs because of an increase in the number of notifications held by the Notification Service. For optimal performance, the number of notifications must be less than 150.

To reduce the number of notifications:

• Start the Notification Client.

• Delete the notifications that are no longer needed.
