The same settings can be used on different televisions

I am interested in buying the premium version of Televizo, The problem is that my dad don't know how to use the app very well, I would like to know if after purchasing the application tivimate I can log in with my username and password on my television, Configure an M3U playlist, which I have, and go to my dad's and my wife's TV and install Televizo, Log in to a registered Televizo Premium account and the other TVs will already be set up in the app
