Still unable to turn on two-factor authentication even when the Set-up button is present
The 'Setup Two-Factor Authentication' button is present on both my Macbook running OS X El Capitan and iPhone 6S running iOS 9.0.2, but when I click on it on either device I get the message 'Two-factor authentication is not available for your Apple ID at this time'. Anyone else getting this. I thought the setup button only appears once it's available for you to set it up.
iPhone 6s, iOS 9.0.2
