Okay, so, i *think* I've got it to work...
You need to set the
Published date in descending order (with the month descending, as well as the year), first book most recent date AND have the folder sorting with a preceeding series order
This combo seems to work...
The other date field seems to make no difference.
Also, if changing books that are already on the device, you need to remove them,
unplug the device so it can refresh, and then re-copy them...
Just going to double test this now, but seems to work
EDIT: YES - i can confirm this works
Thanks for all the help!!!
