Aah thanks for that.
In fact I didn't know what defined the front cover, so this is all new and very useful info. ta.
Kobo version is 1.9.17 - which, now I have noticed that, is I hope about to change - an update has been initiated (at least, I hope it has!)
I think I might well have been hitting the Fat32 limit as I certainly have 1300 or so books on board.
The symptom is, that when I read a book, I see the first page (= cover image) fine. When I sleep, I see a basic, blank, book icon instead.
But if I am hitting the Fat32 limit, there isn't much I can do. It doesn't really matter it is just a minor irritation. But as I have paid* for it, I want to see it! :-)
*some weird psychosales thing going on - if I get something for free, I am grateful for it to work at all. If Ipay for it, doesn't matter what sum, little or great, it better darn well work. Perfectly. All the time. Or else.
