Japanese 1- Missing Audio?

I am using this application on mobile and words with ‘throat’ and ‘i am sick’ seems to be missing audio. Anyone have this problem?

Is it the Memrise Japanese 1? In that case this course forum thread discusses issues with this Memrise Japanese 1 course.

If this is the right course, post a link in the mentioned thread and you probably will get a positive response.
If you are studying another course, please post the link.
