Hi,
Book 1 Lesson 1, in the multiple choice section when it displays the character 他 it has two options of 'ta' in pinyin. One is correct and one isn't; however, there are two ways to type the character, there should not be two pinyin options.
Another issue I came across, was when we type Taiwan in the listen and type responses in various lessons, it will accept 台 but not 臺 which is technically the correct way, right? Hope we have the option to type either. Thanks in advance, let me know otherwise.
