How do I check sample rate via BluOS app

Ok I am struggling to find out how to display sample rate of music playing in native BluOS app. The Bluesound site give instructions to click on contextvmenun of an item in playlist or now playing and select technical info. This technical menun is not present at all on the latest, Android app. Has something changed or is it located somewhere else? All I see is info and nothing in third about sample rate. I can see a HR symbol spmi know its not cd butmk would like to know exactly what it is.
