If you need help, forget it
I lost an 8-year library of over 100 books because my Audible app, downloaded from Google Play 8 years ago, did not sync to my Amazon account and Audible couldn't figure out why. I can provide evidence of 8 years of subscription payment history but Amazon says I'm not a subscriber. My listening experience great but their customer service is non-existent. If you have a problem just give up
