Love Amazon but not this app. Overwhelming, loaded with unwanted recommendations aka ADVERTISING. Does not allow user to sort by shipping date or user preference, dumb. App's Push Notification of shipment and tracking is excellent. Have been Amazon customer since its beginning. App was five star, now only one, even less than one. Outside of app, email notification of shipping gives no details, and requires login, dumber than dumb. Not user friendly. Serves Amazon but not the user.
