Why don't all of my collections show on the home screen of my older generation Paperwhite? One used to be there, then vanished. One I just created doesn't show up. If I look under Manage my Content & Devices, all collections are visible, but not on my device. Any ideas?
first thing you need to do is set your Home page to look like this:
All (highlighted) | Downloaded ___ Collections ___ Title
and on each one that does not have a star beside it, long press until a menu comes up and then select Add/Download to Home or something similar. Repeat until they are all starred then change your Home page to this layout:
All | Downloaded (highlighted) ___ All Items ___ Collections
