I don't have that setting on mine (via desktop); I wonder if it's only being rolled out in certain countries, or rolling out progressively? I'll have to check it again before 27 November rolls around...

fwiw on iOS: - not on by default - under (controls bars) -> Data & Privacy -> Personalized Shopping
