Here is the email I received from Customer Service at The Great Courses:

"Thank you for your email and your question.

The free lectures in your digital are for streaming only, they cannot be downloaded. We have recently updated our Android app so the lectures can be cached on the app to listen offline. If you do not have the most recent version of the app that allows this, please go to the Google Play store to update the app. Please let us know if you have additional questions at this time.

Thank you for your interest in The Great Courses."

If someone has the android app and can figure how to download, please let me know.
