I got my confirmation E-mail in Chinese, because some clever programmer means if someone signs up being in Taiwan he must be capable of reading Chinese. Well, I'm not. Also the websites are popping up in Chinese and I have to change to English every time.
It is not OK to look at an IP address and make the assumption that the individual can read and write in Language where the IP addresses country is.
Very bad design from the web page developer.
The good thing is that you even not can mail to Spotify to tell them their problems.
Any suggestions or help possible?
