-If you previously installed OIDC or used `zone_sync` in the stream-snippets in [v4.0.1](https://github.com/nginx/kubernetes-ingress/tree/v4.0.1) or earlier, and you plan to enable the `zone-sync` ConfigMap key, please remove `zone_sync` from the old [stream-snippets](https://github.com/nginx/kubernetes-ingress/blob/v4.0.1/examples/custom-resources/oidc/nginx-config.yaml#L7).  Otherwise, NGINX Plus will encounter duplicate directive error `[emerg] 13#13: "zone_sync" directive is duplicate in /etc/nginx/nginx.conf:164`.
-Once upgraded, remove the [old headless service](https://github.com/nginx/kubernetes-ingress/blob/v4.0.1/examples/custom-resources/oidc/nginx-ingress-headless.yaml) deployed for OIDC.
+If you previously installed OIDC or used the `zone_sync` directive with `stream-snippets` in [v4.0.1](https://github.com/nginx/kubernetes-ingress/tree/v4.0.1) or earlier, and you plan to enable the [`zone-sync` ConfigMap key](/nginx-ingress-controller/configuration/global-configuration/configmap-resources/#zone-sync), the `zone_sync` directive should be removed from `stream-snippets`. 
+If you encounter a duplicate directive error, `error [emerg] 13#13: "zone_sync" directive is duplicate in /etc/nginx/nginx.conf:164` it is likely due to `zone_sync` being enabled in both `stream-snippets` and the ConfigMap. Once upgraded, remove the [old headless service](https://github.com/nginx/kubernetes-ingress/blob/v4.0.1/examples/custom-resources/oidc/nginx-ingress-headless.yaml) deployed for OIDC.
 
-If you want to enable TLS for zone synchronization for NGINX Ingress Controller, please refer to the [advanced configuration with snippets]({{< ref "/configuration/ingress-resources/advanced-configuration-with-snippets.md" >}}) and example snippets available in the [NGINX documentation](https://nginx.org/en/docs/stream/ngx_stream_zone_sync_module.html#zone_sync_ssl) for zone_sync_ssl.
+Zone synchronization with TLS for NGINX Ingress Controller is not yet available with ConfigMap. If you would like to enable Zone Sync with TLS, please remove `zone-sync` from ConfigMap and add Zone Sync parameters via [`stream-snippets`]({{< ref "/configuration/ingress-resources/advanced-configuration-with-snippets.md" >}}) similar to this [example](https://github.com/nginx/kubernetes-ingress/blob/v4.0.1/examples/custom-resources/oidc/nginx-config.yaml)] and adding the [zone_sync_ssl directive](https://nginx.org/en/docs/stream/ngx_stream_zone_sync_module.html#zone_sync_ssl) along with any other TLS parameters to the `stream-snippets`. You will also need to manually add the headless service, similar to [this](https://github.com/nginx/kubernetes-ingress/blob/v4.0.1/examples/custom-resources/oidc/nginx-ingress-headless.yaml).`
