iOS HDMI Out and WD My Cloud App

I am having the same issue. I want to use my Ipad and Iphone to stream video from Mycloud to hdmi Tv sets. I can’[t do it. All I see is the video playing INSIDE a window on the tv’d display of the  'phone" or “ipad”. As this was a major incentive to get the Ex2 and set up Mycloud I am very dissapointed. Does anyone know if/when WD will address this is a future version of the IOS app?

Thanks
