Dashboard Access Key permissions

The document is accurate; the ability to control access to a shared dashboard by a combination of Organizational associating and access key alignment is limited to SL1's Classic dashboards at this time; AP2 Dashboards do not offer such granularity provided the ability to be private to the user, shared with all users of dashboards regardless of Organizational alignment, or accessible only by dashboard users of specific Organizations. If you would like to request such access controls I encourage you to post on our Ideas Hub stating the behavior as well as the use case(s) for which you would expect this to address for you.
