Mycloud home duo sync issue

hi, a family friend has a mycloud duo and has found that the sync has stopped working properly.

i’ve logged a support ticket but it was closed with no update, a second ticket has been logged for a week with no response

further details are…the sync function has stopped working properly on my device. i am able to sync a folder on the PC over to the NAS which does appear to work and copies the contents to the NAS however any changes made to the folder or folder contents on the NAS are not replicated back to my PC. Can you please advise if this is how it should work or should the “sync” be two way as i’m expecting it to be?

Here are some knowledge base articles from the WD site that may help. if not and you have not heard back from WD support I would suggest giving them a call to check status on your ticket.
