I had a really annoying bug with my account. The "my bookshelf" icon is supposed to show the last three books that were added. Mine displayed the same three random books, all of which I disliked and had rated 1 star. After it didn't go away over a couple months and updates, I contacted their "support". It was a bit annoying to see the same three books I hated every time I went to add a new book and rating. I was told they would look into it and fix if. After a few months passed, I contacted them againthis time I was told it was reported, they were sorry it was annoying, but that no one was working in it... it was in their queue, but no promise could be made they would ever do anything about it. Subsequent contacts I always got dismissive responses from the same horrible agent. After a year and a half of having this bug, I gave their app a one star review. I got an immediate developer response that they were looking for a fix ASAP (public criticism seemed go get their attention in a way private contact did not)too bad this turned out to be a lie to make them look better to those reading my negative review. If has now been two years since I reported the issue, and months since their second promise of an ASAP fix. Nothing has changed, and the customer service rep is as dismissive as ever. I finally deleted my account. Amazon is apparently on with buggy and unsupported apps and paying people to treat their users line garbage.
