Its okay

Generally, the app works well, but very frustrated by the lack of functionality in some areas. For example, figuring out how to enroll in a course or a specialization was not intuitive and took a few days to figure out. Additionally, the app does not allow users to complete peer review assignments (and attempting to load the coursera website on an ios device results in an immediate redirection to the app, leaving no workaround) - this means that it is not possible to pass some courses.
