I am considering buying android tv for my family. I'm curious about switching multiple accounts within the app, I've seen many posts confirms it can switch multiple 'Google' accounts. However, in my case I have 1 google account with multiple 'Youtube' channels, Can I swap between them in the app like i do on web or even mobile app?
Kinda sorta, yes. You have to sign out first rather than just "switch", but you'll be presented with the choice to use any google account registered, then any Youtube account associated to it.
Note that no password will be asked, tho. Anybody in the household be have full access to any of those accounts.
