Apple Magic Keyboard Does NOT Work with KINDLE App AFTER iOS 15 UPDATE Fix
Release Date: 09/03/2022
It seems that everytime Apple does a major update to iOS 15 it changes the settings on the Magic Keyboard so that it longer works with the Amazon KINDLE App.
I searched the Internet and found some solutions but they were for other iOS versions and not version 15.
Quick fix. Settings, Accessibility, Keyboard and turn off Full Keyboard. Click yes to allow the change then test the Kindle app.
