Problem:

My mobile course progress is not appearing on the website. The course progress is not in sync with both the devices. E.g. I started the course 'Intro to Python' on mobile and am halfway through the first chapter, but on desktop the 'Intro to Python' course is still at 0% progress.

Background:

At this time, course progress is not shared between the mobile and the desktop variant of a course. While the courses on the mobile app can be found in the desktop application, and covers the same topics, they contain different content. We suggest completing courses on both the mobile app and the desktop app to be completely well-versed in the covered topics.

Answer: 

If you completed a course in the mobile app, when you navigate to the desktop view you will see that there is a mobile indicator at the top right corner letting you know that you have completed the Mobile version of this course. You will also see an indicator for desktop progress. The screenshot below illustrates and highlights both.

Keep in mind that both the mobile course and the desktop course count towards your total XP (indicated next to your username). So if you finish the first chapter of a course on desktop, and then do the corresponding chapter on mobile, you will receive XP for both.
