To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
I have the same error below with my kindle paperwhite 7th gen. When reading it, it kept shows "error, please delete it from the device then add it again". Very disappointed. I resetted and updated my kindle firmware to ver 5.9.4. but no use. Still struggling to solve this issue.
I bought this digital book for my daughter's kindle. It is a Christmas present and I hope my daughter enjoys reading in the holiday trip. When reading it, it kept shows "error, please delete it from the device then add it again". Very disappointed. I need to find a way to return it but Amazon does not seem offering a way to return a digital order.
