Update, 9:53 AM PT: Amazon’s updated the Kindle iOS app to fix the bug, and the updated app is in the App Store now.
After fielding complaints from users of its iOS Kindle app of reset reading settings and missing books following an update, Amazon is now cautioning its iOS users against downloading the latest software update to its ereader app.
TUAW spotted the warning from Amazon Wednesday morning. Amazon posted a note on the app’s page in the iOS App Store that read “There is a known issue with this update. If you are an existing Kindle for iOS user, we recommend you do not install this update at this time.”
Complaints lodged by users who downloaded the update include one who said the “upgrade erased all content on my iPad, including all of my bookmarks” and another who said the “update deleted all books from my iPad, and I had to register again, creating a second name for the same iPad. It’s like starting all over again. Now I have to upload over 130 books from the cloud.”
