Missing Kindle books after OS upgrade
I upgraded from a 2008 desktop running El Capitan to a 2017 desktop running Catalina 10.15.7. Most apps and files transferred with Migration Assistant, but not Kindle books, just one that I had left open. I can turn its pages and read it ok. The others are represented by black "shadows." They're not readable. Will Kindle books be in Time Machine? (In El Capitan I had iCloud turned off due to another issue.) Should I go into Time Machine and try to bring them forward, or would the 64 bit vs. 32 bit situation require some kind of special procedure? I have Kindle 1.30.0.
