+
+If your Argo Workflow is not being picked up by the Workflow controller after applying it, you may be missing the `workflows.argoproj.io/controller-instanceid` label in your Workflow manifest. This label is required for the Workflow controller to reconcile the Workflow upon its creation.
+
+To fix this, ensure the following label is added under `metadata.labels` field in the Workflow manifest:
+
+```yaml
+apiVersion: argoproj.io/v1alpha1
+kind: Workflow
+metadata:
+  labels:
+    workflows.argoproj.io/controller-instanceid: <instanceID>
+```
+
+The `instanceID` value can be found in the `workflow-controller-configmap`. Here’s how to retrieve it:
+
+```shell
+kubectl get configmap workflow-controller-configmap -n <namespace> -o yaml
+```
+
+Look for the `instanceID` key in the configmap and use that value in your Workflow manifest.
+
+Without this label, the Workflow controller will not be able to reconcile the Workflow.
