Where can I find out which Cloud Rules have been applied to my Project?

Click on the Project Name in any Project card. You will now be in the Project details view. Click on the "Automation" tab. By default you will be presented with the "Cloud Rules" sub-tab. This tab will contain a list of Cloud Rules which have been applied to the Project, along with the details of each Cloud Rule. Cloud Rules can also be created, or existing ones added, on the Project's "Cloud Rules" sub-tab under "Automation".
