Try this as a 'solution" until the My Cloud app is fixed: use a different app.
There is a free, great app called Avia for Android and Kindle. I use it on my Kindle tablet to play music, videos , photos from my device (My Passport Wireless) that uses My Cloud app, as well as any other sources I have that don’t use My Cloud. I love the playlist feature of Avia, too. (See my recent related post here about playlists for more info.) http://community.wd.com/t5/WD-My-Cloud-Mobile-Apps/Playing-from-Playlists/td-p/862992
In fact, I like Avia much better than the My Cloud app.
