 ### Extended attributes (Beta)
 
 :::important This feature is currently in beta
-
 Extended Attributes is currently in [beta](/docs/dbt-versions/product-lifecycles?) for select users and is subject to change.
 :::
 
+:::note 
+Extended attributes are retrieved and applied only at runtime when `profiles.yml` is requested for a specific Cloud run. Extended attributes are currently _not_ taken into consideration for Cloud-specific features such as PrivateLink or SSH Tunneling that do not rely on `profiles.yml` values.

 Extended Attributes is a feature that allows users to set a flexible [profiles.yml](/docs/core/connect-data-platform/profiles.yml) snippet in their dbt Cloud Environment settings. It provides users with more control over environments (both deployment and development) and extends how dbt Cloud connects to the data platform within a given environment.
 
 Extended Attributes is a text box extension at the environment level that overrides connection or environment credentials, including any custom environment variables. You can set any YAML attributes that a dbt adapter accepts in its `profiles.yml`.
