Unrecognized Lecture Format

If you see this message while taking a course on the Udemy app, it means that the lecture you're trying to view is a file type that is not supported by iOS. This happens most often in our programming courses. For example, if an instructor uploads a Python file (.py) as a lecture, the file will not be available on the app.

To view this lecture, please sign in to Udemy from your computer.
