So there isn't audio for Ukrainian lessons?? This is curious, because it is the kind of language that needs audio to be well learnt.
There is audio, just not for everything. At least this is the case for me. Normally it's the first few translations where they show the pictures that the audio doesn't work. I'm not sure if it's meant to be like that or not though.
This is the same case for me. The course is in Beta, so make sure to give feedback to the contributors.
