Many people using Google Nest speakers set up as a stereo pair have been complaining that they are receiving the following error when trying to change the volume..
Sorry, I can’t change the volume on this device !!
Unfortunately, the problem stems from a legal ruling against Google from Sonos who say that Google infringed a patent relating to the volume control of multiple devices.
Google announced the situation on a community blog post shortly afterwards.
Since the update users must now adjust the volume of a speaker group or pair individually leading to many users being rightfully angry about the situation and saying that it renders the speakers “Not fit for purpose” or “useless”.
