Google has announced today that it’s expanding the Voice Match feature on Google Assistant to support separate Netflix profiles, via Android Authority.

Now, you’ll be able to attach individual Netflix profiles on your account to the various Google profiles you have set up on a Google Assistant device (like a Google Home). Just like Assistant can offer personalized information through Voice Match for bringing up calendars or commute times, now, (at least in theory), when you ask Google Home to play Netflix on your Chromecast, it’ll pick up where you left off in the middle of your Friends marathon, and not your sibling’s Altered Carbon binge.
