I downloaded the trial and am testing the workflow action pack–move folder action. Currently, it is doing a “copy” of the folder. the folder remains in the source library. When I created the workflow, I did it as a SP 2013 workflow and followed the video posted here: https://www.bing.com/videos/search?q=sharepoint+designer+2013+workflow+move+folder&view=detail&mid=6006180C57E2D9A7A96A6006180C57E2D9A7A96A&FORM=VIRE
Additional data: This is being used in O365
Thank you for your message.
Could you please send the screenshot of your workflow?
