I've noticed that "Download metadata" in Calibre 2.48.0 Windows 64-bit doesn't work like in previous versions. I can't tell with which version the problem started.
Effect: "Download metadata" isn't downloading the complete description text. The description texts on Amazon are divided into three categories: "Short Description", "Review", and "About the Author". In previous versions, Calibre would fetch all three texts. Now it only fetches the text under "Short Description". This happens with the pugin set to "English" and "German". Examples are
Abaddon's Gate: Book 3 of the Expanse (English, ISBN 9780748122981) and
23 Lügen, die sie uns über den Kapitalismus erzählen (German, ISBN 9783641041403). The plugin was set to the book's language (country) for each test.
A fix would be much appreciated, as copying/pasting and manually editing the descriptions is very time consuming (; .
