I was initially able to setup through “Sync to My Cloud” back up of a few folders. Then “Sync to My Cloud” on right click disappeared. I finally reinstalled WD Discovery. The “Sync to My Cloud” reappeared and began backup with duplicate folders. Then it stopped working. I rebooted and now “Sync to My Cloud” is gone again.
I am beyond frustrated! I used this with my Windows 7 machine for almost a year with no issues!
