Since Rise 360 uses secure
https, embedded content must also use
https to work properly. Make sure the source URL for your content starts with
https—assuming the website that hosts your content supports it.
If your URL starts with
https and your embedded content is still missing in Rise 360, test the URL in this security checker. Sometimes the hosting site is secure but the content itself isn't. The security checker will let you know.
