I've created a kids profile on Google TV and it's working fine; you can't leave it without typing a pin. The problem is that if you're in an adult profile when you turn off the TV you'll still be in it the next time you turn it on. Most of the time I remember to switch to the kids profile before I turn it off but sometimes I forget. Is there a way to timeout a profile login or some way to make it so you have to enter a pin every time?
EDIT: I realized I should have made the title "to prevent", sorry if this was misleading I don't think I can change it but my question is about preventing kids from accessing adult profiles.
I'm dealing with this same issue now also as I've come down in the morning one too many times now to find them deep into a YouTube black hole of content they should not be viewing. This seems like an absolute no brainer and literally every other app as figured this out. Start up from the profile screen, require a pin for the adult profiles but let switching between kid profiles happen without pin. This seems too simple. Why do they have to make it so backwards.
