Chapters not always marked complete in Webtoon Mode

[duplaja]

What happened?

When binge reading, I notice that often (maybe 1 or 2 out of every 20 chapters) are not marked as complete when reading. You can read past that point, and there's no issues during that current session.

When resuming reading, however, resume starts at the first chapter that's not marked finished, which can often be well away from the last chapter with read progress, where you actually left off.

To fix, you have to go to the series view page, and manually mark the chapters as complete.

Additionally, there's an interaction on mobile sometimes, where if you load up a chapter that's not quite finished, and scroll to the bottom, when you visit the next (completed) chapter, it auto-scrolls repeatedly to the bottom of that new chapter, triggering the new chapter load, and scrolls through that one as well, cycling until it gets to a chapter that's not finished, or you manage to quickly counter-scroll to stop it and back out.

What did you expect?

Chapters should be marked as complete when finished (root issue). Alternatively, continue reading could jump to the last chapter with read progress on it that isn't finished, rather than the first.
