I just started learning mandarin chinese with drops and I’m really enjoy it, thanks for the great app! However I’ve noticed inconsistencies in some symbols. For example, the “yán” symbol that the app asks you to drawn is different from the “yán” symbol it shows you when it teaches you. The difference seems little but it confused me, because I don’t know which is the right one. The same thing happens with the “yòu” simbol. It is shown as a single straight line when the app asks me to drawn, but as a 3-stroke symbol afterwards. The difference in this one seems bigger and more dramatical, because a single straight line is also “yi” symbol. So far I’ve noticed this kind of inconsistency in: chuò, mián, yòu, mì. Are these inconsistencies supposed to be there?
