Most recently opened lesson does not appear in my lesson list

I have just imported a YouTube video and read the entire lesson.

When I list the course contents, it correctly appears as the most recently opened lesson. (see screenshot #2 below)

Problem:

  • it does not appear in my lesson list. (see screenshot #1 below)
  • To retrieve it, I need to visit its course where it still correctly appears as the most recently opened lesson.

Additionally,

  • A lesson from the same course I had opened previously 1/does appear in the list, and 2/is wrongly listed as the most recently opened lesson (see screenshot #1 below)
  • I later imported another video in the same course, and it correctly appeared my lesson list.
  • I repeated this sequence to no avail: there is no combination of actions that makes this lesson appear in my lesson list.

The problematic private lesson id is 43649794

Thanks for reporting. We will look into this.
