I wrote a negative review a few years ago highlighting serious issues w/ the app. I loved the app, but hated its issues. My hope was the money behemoth that is Amazon could fix it. I no longer love the app despite its issues. Amazon's integration has killed the best parts & kept the worst. It's now a clone of the mediocre Kindle app. Worst is the loss of series sorting. I am overwhelmed by choice now and can't navigate it anymore. Feel like I've lost all my past purchases. So much $$$ wasted.
