Problem with Microsoft Windows 10 Mobile app

You are comparing apples to oranges. This discussion centers on the Microsoft Windows Phone mobile app which WD discontinued last year and currently has no plans to update and reintroduce. Windows Phone users can use a “file manager” app to access the My Cloud while connected to the same local network. For remote access the Windows Phone users can use either; FTP (which is insecure) or use a web browser and access the MyCloud.com user web portal.

Per netmarketshare.com:
The DESKTOP market share for Mac OSX is 6.43%.
The MOBILE market share for iOS is 25.75%.
The MOBILE market share for Windows Phone is 1.95%.

Mac OSX users can use either the Mac Finder to access and map their My Cloud across their local network, use Apple Time Machine to backup their Mac across the local network. Use the WD Sync program (http://support.wdc.com/product.aspx?ID=904#WD_downloads). Use WD My Cloud Desktop program for Mac OSX (http://setup.wd2go.com/?mod=faqs&device=mc&faq=accessComp). Or use the MyCloud.com user web portal.

WD has apparently decided it is not worth their time/money/effort to support a mobile device (Windows Phone) that currently garners less than 2% of the entire mobile device market. and over time (per Netmarketshare.com trends) has had a high of only 3.14% market share (for one single month last year). It should be noted WD doesn’t have an app for Blackberry (at 1.09%) either.
