BrightSign’s OS version 8.2.72 and BrightAuthor:connected version 1.6.29 contain a new feature that lets users see and modify settings using the BSN.cloud Properties Panel or through the BSN.cloud API. To avoid backwards compatibility issues, the supervisor won't honor these settings unless it is first enabled in your custom Device Setup Package, custom presentation, or custom application/plugin.
This feature is natively supported and enabled in BrightAuthor:connected presentations using version 1.6.29 or later, but you must enable it if you are running custom scripts. This document describes how to enable this feature.
