Different progress between web and mobile app

I’ve been attending the M001: MongoDB Basics

Initially i used the iOS app but when a computer was required i changed to using the web page from my computer.

Now, when returning to the iOS device, my progress don’t seem to have been updated according to the progress of my course.

Also, I might add, the progress could be shown a bit more clearly. I would want somewhere where i could go to see unfinished tasks for myself at a specific course. Something like a TODO list.
