Is it possible for the user with full control ("You are not authorized to respond to this task." message ) to re assing a flexi task that is pending. task is enabled for delegation, but the site admin doesn't have access to edit the task or re assign the task.
I have gone through many (Re-assign a workflow task that is not assigned to you | My SharePoint Adventures ) dont know if the task owner is available through the nintex workflow.
cant seem to find a solution for nintex workflow, maybe I am missing something, please let me know if you have a solution for this.
