There are a couple of ways to review your notifications in the Margo dashboard. For a quick view, simply click the bell icon in the top righthand corner.
A drop-down will appear with an overview of your notifications. To dismiss one, click the X, to dismiss all, click "Mark all read." To view the rest of the notification details, click on the title and it will appear in a pop-up window.
The other option for viewing your notifications is located within your inbox. Select the envelope icon in the top right corner. Dismiss the new chat pop-up, and select "Notifications" in the top tab. This is a great way to view your notifications if you have plenty of them to sort through.
