Syncing Issues with Books Read by Alexa with Kindle Assistive Reader

Kindle book doesn't sync to the furthest page when Alexa begins reading.

Alexa starts reading from the most recent page read on any device. To help set context, Alexa may start reading from the previous paragraph from your most recent page.

Try these troubleshooting steps if Kindle Assistive Reader isn't starting from the place you last read across any device:

Open the book on the Amazon device or Kindle reading app where you were last reading.
Confirm that the device has internet connectivity, and then open the book you were reading the book manually to the furthest page read.
Select the menu icon and sync the book manually to the furthest page read.
Once sync is complete, ask Alexa to play your Kindle book. Reading will pick up from that location.
