Recent updates render these devices as paperweights! If we ask Google to play music on a speaker group, 99% of the time it will say "sorry something went wrong". The other 1% it still says "sorry, something went wrong" but then will succeed in the command. We've invested quite a lot of money on our devices and the inconsistencies in their operation are infuriating. We got to enjoy having all of our smart speakers working in unison for all of a week after this recent update, but it's broken now.
