Global Address validation doesn't work

[sheykholeslam]

I'm trying to validate a Canadian address using my Test API token but it doesn't work and returns nil.
Based on documentations, If I want to validate a non-U.S. address using my Test API token, the API should pass back the address information without performing any validation but what I've received in Address object is "validation_results"={}. I tried it we the Berlin address which was provided in examples but I got the same results.
