Dashboard external pages no longer support dashboard URLs
23.2 Release notes state that external pages in dashboards will no longer be able to reference dashboard URLs.
Our organization heavily relies on this functionality for layouts, providing a customized experience for groups to be able to access all of their important information in one spot similar to a landing page via web. This not only streamlines training, but is a important one click selling point for our director +. Groups can customize dashboards with links to all reports, dashboards, forms, etc all in one place without having to have an extended onboarding process.
