Currently the reading progress gets updated as soon as a chapter is opened when it should ideally be updated when the chapter is completed i.e navigating away from the last page.
EDIT:
My reasoning is that "reading progress" seems to imply "i've read up to and including this chapter".
I would suggest that the trigger be placed when the last page of the chapter is loaded on-screen which would better indicate that you have read that chapter.
Just opening the chapter doesn't seem to fit the criteria of "read" in my opinion.
in the sticky under miscellaneous "Sync read markers with progress tracker" also seem to indicate that the reading progress should reflect that the actual chapter should be read before being added to the progress.
