How do I delete non-existent notifications?
There are two ways to delete nonexistent notifications:
You can click on the New Updates bubble that appears under your Username in the upper right of your browser window. A Notifications pop-up will appear. Click on the X next to the notification you’d like to delete.
Or you can navigate to the My Profile tab in your browser window and click on My Notifications. A new page will appear listing all of your notifications. Click the X next to the notification you’d like to delete.
