I have NEVER had succes with Kindle or Audible in transferring to a new phone. This time, I just deleted everything from downloads on both. What often happens is the Kindle book will show as not being authorized, and you need to delete and re-download. PLUS there is a benefit if a book has restrictions on installs. If you remove it from the old device, it will NOT count against the install count on the new device. I have used a wireless stand for a year with the 8 plus, and the only time I have a problem is if the phone wasn't centered properly. In which case I plug it into a lightning cable connected to a USB-C charger, and FAST charging takes over. I am liking my XS more and more, but a small part of me would exchange it for an XSMax. and maybe when I actually use one, I will. But so far, this has been a good weekend of playing with new Apple toys.
