It’s like this on my dashboard and on the book page. I can’t find any way to edit activity anymore.
Usually I do a progress update and then edit the activity update to manually set the starting page. If I do a progress update it always puts the starting page as the previous update’s ending page, but it doesn’t work like that for manga. If I read to page 78 in one session, I’ll start on page 79 the next session. So this is why I would really like activity editing to come back, because I also can’t add anymore activities myself outside of the progress update mechanic. (Btw, does that mean I won’t be able to easily batch add old reading progress via a book’s activity section? )
And I just noticed I also can’t remove spurious activities anymore, only ‘hide’ them (but then I still see them, so that’s also ruffling my neuroticism).
