Why won't my classes load in the mobile app? My mobile app is not behaving as expected. The Udacity iOS and Android Udacity apps can no longer be downloaded and are not supported after January 9, 2019. We apologize for any inconvenience this shutdown may have caused you. Rest assured that your Nanodegree program remains fully accessible on your mobile browser and that all your progress in the Classroom is saved. Udacity content and services like the Classroom, Knowledge and Student Hub, remain accessible on a mobile browser experience. While we can’t promise a release date of a new Udacity App, we are working in the coming months to determine the best way to support our students on mobile experiences. To access your content, you can always sign-in using your email and password on udacity.com in your mobile browser and you will be redirected to your mobile classroom.
