if you are in another country the website/app should automatically detect your location, head on over to https://www.spotify.com/account/overview/ click edit profile and there should give you an option to change country
I have the SAME problem. I live in Canada and when I use your link my ONLY choice is US. Shouldn't you be able to see my country when I first installed instead of waiting 14 days to tell me?? There has to be an EASIER way to change my country.
