Hi Boxmodern,

 

In addition to the previously mentioned steps, this issue is directly related to Chrome’s new enforcement approach for embedded content. Only the host application (Power BI Service / Fabric) can change iframe permissions; custom visual creators are unable to override this in their code. Microsoft needs to update their iframe sandbox settings, since the absence of the allow="local-network-access" attribute stops Chrome from passing user-granted permissions to embedded frames. Until Microsoft releases an update, organizations relying on internal network assets should keep an eye on the Microsoft 365 Roadmap and Fabric Known Issues pages, as similar browser permission changes often lead to gradual service-side updates.
