Today I updated Nintex Workflow 2013 to version 188.8.131.52. After that is no longer possible to use the "Lazy Approval" functionality. I can see the response in the Drop folder and the mail will be processed by SharePoint (no longer visible in the folder after a minute) but the task will never be approved or rejected until I connect to the "Workflow Task" site an do it. It worked like a charme it the past with custom lists. I have no idea what the problem is!
Thanks in advance!
