Did anyone else notice that the Vocabulary Builder has been downgraded so that side loaded books can not use this feature?
"Note: Vocabulary Builder currently supports content purchased from Amazon.com and personal documents sent through the Send to Kindle application or Kindle Personal Document Service. It does not currently support personal documents that were transferred to your device via USB. To learn more, go to Send Documents and Web Pages to Your Kindle."
Also, for those that use it, Goodreads is still only working for Amazon purchased content and the cloud sync pop up when creating a new collection is still not fixed.
Besides these points, its not a horrible update.
