I regularly use my Kindle and my iphone 7 to read a book. They synchronize instantly when I go from one to the other.
I just acquired an old mini Ipad with IOS 9.3.5. No problem loading the KINDLE app and the books I have on the Iphone and Kindle.
My difficulty is that Ipad refuses to sync with the iPhone or Kindle.
He only offers me to go to the last page read on the Ipad ...
On the KINDLE website, my new iPad appears well.
Thank you for your advice
