 * **KOTS Auto-GitOps workflow not supported**: Embedded Cluster does not support the KOTS Auto-GitOps workflow. If an end-user is interested in GitOps, consider the Helm install method instead. For more information, see [Install with Helm](/vendor/install-with-helm).
 
-* **Downgrading Kubernetes not supported**: Embedded Cluster does not support downgrading Kubernetes. The admin console will not prevent end-users from attempting to downgrade Kubernetes if a more recent version of your application specifies a previous Embedded Cluster version. You must ensure that you do not promote new versions with previous Embedded Cluster versions.
+* **Downgrading Kubernetes not supported**: Embedded Cluster does not support downgrading Kubernetes. However, the Admin Console does not prevent end-users from attempting to downgrade Kubernetes. To avoid issues that could be caused by downgrading Kubernetes in customer installations, do not promote new application releases with Embedded Cluster versions that are earlier than the version used by the previous release.

However, the Admin Console does not prevent end-users from attempting to upgrade to a new application release that specifies a Kubernetes version more than one minor version later than what is currently installed. To avoid issues that could be caused by skipping a minor version of Kubernetes, Replicated recommends that you select **Prevent this release from being skipped during upgrades** when you promote a new application release that increases the Kubernetes version.

 * **Templating not supported in Embedded Cluster Config**: The [Embedded Cluster Config](/reference/embedded-config) resource does not support the use of Go template functions, including [KOTS template functions](/reference/template-functions-about). This only applies to the Embedded Cluster Config. You can still use template functions in the rest of your release as usual.
