This is the worst switch I've ever seen from google. Upgrading from the Fitbit login to the Google login has created a disaster for family accounts. You can no longer see your kids activity as they're no longer visible through your app. It requires each kid who shouldn't have an email account to have a Google account. Furthermore kids usually have Amazon tablets. You cannot download a Fitbit app on an Amazon device so the kids can't even track themselves. What a horrible change with no fix from Fitbit.
