I am not at all happy that Google have stripped away yet more features from the Home App. Namely functionallitly around speaker groups. I have a lot of google home products and it is unacceptable that the features I want most have now gone. Turning up speaker groups with hardware buttons when the screen is off and being able to alter all volumes of the whole group at once. I wouldnt have purchased the products without this functionalitly. Utter shite and getting worse all the time
