When your Notifier gets very full, you may find it more difficult to locate important messages. They can tend to get buried under other messages. Here is how to clean up your Notifier:
1 - Click Show More for as many times as it will let you.
2 - Click Select All.
3 - Click Dismiss.
4 - Click Refresh.
5 - Repeat until nothing else populates.
If you make sure to dismiss messages as you are finished with them, your Notifier will remain clear and organized.
