One usually needs to use an app on phone to play media from My Cloud, (or any source) and the app must be capable of casting to Chromecast. Not all are.
Thanks Mike for reply , so it’s a matter of what media player app am I using? I think I will try more than one till it’s done … Thanks again
For your Android phone, look in to free and nice Avia app.
Many thanks, I will try it and let you know
