I uploaded all my books with covers since I have my KT, even if it was almost useless before (just that small cover when I kept touched on a book name).
Since latest update 5.3.2 introduced cover view for my books all this work was finally useful but I have an issue: not all book covers are properly sized.
Most (if not all) Calibre uploaded books have smaller cover than the ones bought on Amazon Store.
Also some directly converted .epub have the proper cover size, but all the covers I manually added on Calibre are small, even if the cover I added in the metadata was fine and big enough (not some sort of thumbnail mode cover).
Is this a known issue?
