Amazon Alexa is cool but I am having a hard time getting progress with Alexa. I ask questions Alexa doesn't understand me, I can only ask basic questions and set reminders. when I want to hear audio book, I have no idea where Alexa gets this book it reads but I am not at all interested. I ask how do we train to understand each other. no response. I have to use the app list to do something different. I am really let down. I cant ask anything but news I am interested in. I cant figure out how.
