it doesn’t’ work
Could you post
- a link to the course,
- any error message,
- screenshot
- what you think should happen that doesn’t happen
- and you platform/version
It would be much easier to give any suggestion. May sound a lot of work, but give what you can do most easily and it gives a start.
PS: when I play Meet the Natives on for example Memrise’s Korean 1, it plays videos with people saying the phrases. So you that is what you can expect.
