Bing Translator for Mandarin to Spanish needs a major overhaul.
Bing Translator for Mandarin to Spanish cannot translate full sentences at all, and occasionally fails on single words. Furthermore, it does not show any pinyin at all, and does not show any alternative translations. At least 1,500 people speak Mandarin and 650 million speak Spanish. Needs to improve.
Please know that Pinyin is still there. Once you have translated into Chinese you can swipe left and you will find Pinyin.
