Chromecast not working with WD Cloud App

I’ve been trying to get the new WD Cloud App to work with Chromecast but not having any luck.  I’ve updated the lastest WD Cloud from the Google Playstore and updated my My Book Live driver to the latest version (MyBookLive 02.43.10-048 : Core F/W).  I have a Samsung Galaxy 5 and also a Samsung Galaxy Note 4 and also I can successfully cast Youtube and even my screen I cant get the native WD App cast to work.  When I select the cast icon it plays the movie on my device but all that displays on my TV is the words Western Digital on a gray background. 

Thanks for any suggestions people might have!
