Offline not useful – Coursera: Grow your career Review

Courses are great but this application made poorly. Courses are able to download offline but to use it in flight you must keep course open. If you didnt open your course before trip - you got a surprise - it fails to open and all downloaded content is not available. Also I have constant problem on rotation when notes pop up and I cant remove it without closing and reopening video. And generally application controls feels unresponsive and hard, like on web page. This obvious problems stand for the year at least and it seems nobody cares.
