As i live in an English speaking country, Sonos would not have to translate any form of documentation.
My guess is that it is a royalty question, like paying Google to use Google Assistance or Amazon for Alexa.
Can you give me the reason(s) ?
I know the standard is answer is; We working on making this available in other countries.
I am quite disappointment that I can buy a Sonos One Gen2 at a host of stores in South Africa, but can not use voice control over its 6 microphones.
