So, this is what your dashboard looks like:
The latest chapter is always on top with the older ones being toward the bottom. (Basically like on Tapas). Now, if you schedule, then the chapters will be sorted by release rate. Like if I scheduled a chapter for today, one for tomorrow and one for the day after that, then the one scheduled for today would be in position 3.
Then there is the latest update section on the front page:
This one basically shows the novels that were updated recently site-wide. So any novel that updates goes there. But here's the thing: Apparently, this doesn't take chapters into consideration that aren't on top of the list in your dashboard. So if you schedule chapters for day 1, day 2, and day 3, then only the chapter from day 3 would show there but not the ones from day 1 and 2 because they weren't (at the time they were automatically posted) on the top of
your list.
I hope it's understandable I'm really not so sure how to explain this well. I can try to find the corresponding thread on the SH forums if that helps.
