Yes, its probably a long shot, but getting nowhere with search and google.
My wife and i have separate profiles on all our streaming services (Apple, Netflix, D+, P+, Hulu, etc). I love the idea of content discovery on Chromecast with Google TV and set up separate profiles for my Wife and I. It seems though when you click to watch something, it goes directly to the last used profile on the streaming service. Does it remember which profile was used per profile, or will it always use the last profile? Seems like this will poison the in app discovery and watch lists. Especially a problem since we only have GTV on our main tv, and the other tvs still have Roku. Just about to cut the cord and trying to figure this out before i return the equipment
It's not a thing yet, but they're working on it
