I have gone so far as to call Apple. 1st level could not resolve. Sent ticket to second level. Second level told 1st level to ask the customer this, this and this (this is such bad customer service) instead of just asking me directly. I was asked to check the following....
"The engineers wanted me to check some settings on the Apple TV with you, can you check the settings below on the Apple TV and let me know if you still have an issue?
System language, Region format and iTunes Store account Location must all be set to English to be able to use Siri in English. "
How does one set a location to English? Isn't "English" a Language and not a country?
I live in Germany. I have an ITunes account in Germany because it is where my Visa card is registered. Using US, or UK, is not accepted by ITunes as my Credit card is a GERMAN. So I have no choice to use the German ITunes. If I switch everything to English and UK or US, it works. But then nothing else does basically.
The advertisement states that in 8 countries Siri would work. It did not say I had to be able to speak the local language. I assumed that I could use English as it is available in the US and UK. Why restrict it to only English only English speaking countries?
Anyway, So now Siri is set to German. Siri doesn't understand me because of my terrible accent. My wife, who is German, gets a kick out of me yelling obscenities at Siri in German. Well at least she is happy.
