Good morning (from here). I have spotted a reason for saying "no audio".
I see on the course you suggested you have black play arrows in the last column called "Audio".
I guess you want us to listen to them at the selecting stage.
What I was expecting, was them to play on answering correctly (or wrongly) like MemRise did.
Also there is no listen to audio and select answer (English typing or the selecting the answer from a choice of 6 phrases). [Feature Request].
