Letters wrong in Android app to type what you hear

Lao Lesson 1 will not let me past a word since the letters given don’t spell what the audio says. Even when I try using a full keyboard it marks it as wrong and keeps me in a loop so I can’t get past that word.

Word is ‘dee’

I have the same problem in Chinesisch 1 with the word ‘rén’ (人). Only the normal ‘e’ is available and ‘ren’ is marked as wrong. Typing ‘rén’ from my (German) keyboard also results in an error.
