If one turns off the SMB1.0/CIFS option in Windows 10 they will have trouble accessing the My Cloud using it’s name and will have trouble seeing the My Cloud in Windows File Explorer. Make sure that this option is enabled/on as sometimes Windows updates can turn off previously enabled options/settings.
If Master Browser is really an issue there is some discussion on disabling this option on the My Cloud using SSH both in the following thread discussion (Windows 10 Specific Method 6 - Third option) and elsewhere (use the forum search feature, magnifying glass icon upper right).
