I am a newbie to Nintex workflow and I hope to get some help or suggestions. I currently have a workflow I'm creating with Nintex WF for SharePoint 2013 on-premise. The WF is a document approval worflow. Once the document is uploaded, a notification gets sent to the Approver in the process and the statuses they have to select from are 'Approval' 'Approval with Comment', 'Further discussion needed' and 'Disapproved'. Depending on what is selected, an email notification is sent to the next person in the process for review and they have the same statuses to select from. I was able to do this with a switch action. What I really need and want to do is to set a 3 days to review time limit for the document when the notification is sent. I tried using flexi but I got all the more confused. I know this can be done but I think my approach isn't the right one. Any idea of how I can send a 3 day reminder to review the document once it's been uploaded and once the approver has updated the document with a status?
Any help would be much appreciated. Thank You!
