If you are having trouble with bixby working on your watch as I have, "error, please try again"... I found a solution that worked for me. If you go to the Galaxy store and search bixby under the watch tab, there is watch bixby voice, and watch bixby. Th voice app is preloaded on the watch but the bixby app is not. Download that app then relaunch bixby. It worked for me hopefully it works for you.
