I Can't Register Kindle on my Old iPad
When downloading Kindle from the App Store it says my device won't run the latest version and asks if I want to download an older version. The download works great, but when I try to register it for Amazon, I get a "Device Registration Failed - No customer found for this e-mail address and password" message. I have 2-factor ID turned on and tried turning it off... same message.
iPad Wi-Fi, iOS 5.1.1
