How do I add CDN Edge Groups to a Billing Plan?
Navigate to ' Billing Plan', click on the graph icon 'resources' button, and scroll to the section of 'Limits of Edge Groups'.
Click the button 'Add New Edge Group', a window will pop up. Select the CDN Edge Group and click 'Save'. You may add multiple CDN Edge Groups into a billing plan. Once edge groups are added into user's billing plan, user would be able to select the CDN edge group upon CDN resource creation.
Multiple edge groups can be added into one billing plan.
