Siri is currently available on Apple TV 4K and Apple TV HD in these countries, regions, and languages: Australia (English), Austria (German), Brazil (Portuguese), Canada (English, French), France (French), Germany (German), Hong Kong (Cantonese), Korea (Korean), India (English), Ireland (English), Italy (Italian), Japan (Japanese), Mexico (Spanish), Netherlands (Dutch), New Zealand (English), Norway (Norwegian Bokmål), Spain (Spanish), Sweden (Swedish), Taiwan (Mandarin), UK (English), US (English, Spanish).

Let’s hope this isn’t a fluke and that it won’t be removed in the next update 🤞
