Error in Russian Instrumental Case Lesson 1
I couldn't find anywhere to report an error, but in Lesson 1 of the Russian Instrumental Case skill "с кем" (to whom) is incorrectly formed.
The "c" is an English "c" instead of a Cyrillic "с" so when you enter the correct fully Cyrillic phrase, it marks you wrong. The only way to be marked right is to type the "c" on the English keyboard and the rest on the Cyrillic keyboard.
If you look very carefully you can see that the "c" is slightly smaller than the usual Cyrillic "с" on the iPhone.
I expect someone must have found this before but just in case ...
Best wishes, Ivan
