I was trying search on the website to see if there is any place I can just file a ticket to the Sonos team, but it seems I can only create a new topic in the Community. Okay.
I came from Taiwan and I a long time user of KKBOX. We bought our PLAY:1 this August and have been loving and enjoying it a lot. One day the idea of trying to stream KKBOX library came to my mind and I googled if SONOS supports KKBOX. To my surprise it does! although for some reason I was not able to add KKBOX as streaming service on my iOS SONOS app. I read further the web page and found that KKBOX+SONOS seems to be only supported in specific regions.
Taiwan, of course is listed as the first one of the supported places, though there are couple of words "province of China" added after it. No offense to anybody, but Taiwan is definitely not a province of China.
