Google made me reset my password. Now Roku plays for a half an hour then i get a notice on the TV saying that I was signed out of the goggle account and sign in again. I cannot find out where to sign in.
I assume you're watching some google-related/owned channel such as youtube?
(I don't use youtube much. but sometimes when I launch youtube, it tells me how much better it could be if I logged in, though I still haven't.)
