Completed lessons do not display as "completed" automatically #141
Description
After completing several lessons in a row and going to the lesson plan, only the last lesson was marked as completed.
Manually marking the lesson as completed works correctly.
A few possibly significant conditions:
- automatic playback of lessons turned off when finished
- part of the lesson was played in acceleration
- after entering the lesson again, it shows a com about the possibility of starting at the ending point 00:00:00
