Hello, I installed and configured a new Apple TV 4K, and in the course of the installation it asked me whether I wanted to use Siri or not. I selected "I don't want to use Siri", thinking that I could activate it later on. But now the Siri option is greyed out, and I can't for the life of me find out how to enable it. I tried to change the location, the language, to sign out from the iTunes account and to sign in again, but to no avail. I cannot get to that prompt again. Do I get only one chance? Once I decided not to use Siri, am I not allowed to change my mind? Do I have to reset the Apple TV to the factory settings and to set it up from scratch? Is that the only option? Thank you.
