We are aware that many users cannot resume the chapter they last read in some manga, and some volumes show more chapters than they actually have (e.g volume shows 6 chapters, but it only has 1 chapter).
Recently, we started updating some series with HD or official scans. We're sure you can notice how images, text, and translation quality are much better now for those series. We also organized old chapters into volumes (just like the released books) for a more continuous reading experience, and unexpectedly caused this issue.
For now, here's some steps that we have taken to reduce the inconvenience & bugs:
Volume names now contain the chapters as well. Eg. Vol 1 - Chapter 1-6
Volume only shows 1 chapter or 20-ish pages etc. : Pull to refresh the chapter list, and it should fetch the correct chapter/vol data
We're truly sorry for this inconvenience caused and thanks for your understanding.
