Yes, we need some guidance from WD on this.
While I don’t have a v2.x single bay My Cloud the user manual for it indicates there is an option within the Dashboard of the v2.x single bay My Cloud to use SMB3. For the older v4.x single bay My Clouds one would have to edit the /root/etc/samba/smb-global.conf file and change the max protocol setting from 2 to 3. More info on changing the v4.x SMB setting within the My Cloud is detailed in Windows 10 Specific Method 6 in the Compilation of Windows 10 Methods, Steps and Solutions thread.
