+### <a name="assign-delete-timeout"></a>Scenario: Assignment deletion timeout
+
+#### Issue
+
+Deletion of a blueprint assignment doesn't complete.
+
+#### Cause
+
+A blueprint assignment may become stuck in a non-terminal state when deleted. This state is caused
+when resources created by the blueprint assignment are still pending deletion or don't return a
+status code to Azure Blueprints.
+
+#### Resolution
+
+Blueprint assignments in a non-terminal state are automatically marked **Failed** after a _6 hour_
+timeout. Once the timeout has adjusted the state of the blueprint assignment, the delete can be
+retried.
