How to transfer files from Dropbox to MyCloud on a mobile phone

The WD MyCloud claimed that I can easily transfer files between Dropbox and Mycloud but I cannot find a way to do so on my Android phone. I can view all my files on Dropbox from Mycloud and can select a copy and paste function to paste to a MyCloud public folder… but nothing happens  

Dropbox compatibility is best experienced with the WD SmartWare Pro automatic backup software utility, which is able to to link to Dropbox. WD SmartWare Pro is a Windows-only application.
