I'm running an iPad retina, and trying to login to the iCloud Drive in the Settings App.
It is logged into the App store, and iCloud sync for the Notes app.
I also have an iPhone 6S and a Macbook Pro Retina. Normally the 2FA verification code (please enter this iCloud passcode) notifications show up on the other devices when doing iCloud related operations. (Turn on iCloud backups etc).
When I try and login to iCloud Drive on my iPad, it asks me to login to iCloud with my password, and then pops up a 2FA verification code entry screen. But the code to enter doesn't come up on my other two devices.
My question is: Why isn't my iPad Retina Cloud Drive login 2FA verification code not showing up on my iPhone or Mac?
Edit: 2FA is enabled on the other two devices. That's how the 2FA notifications mentioned above pop up on the other two devices for other iCloud operations.

Is 2FA enabled on your iPhone and Macbook? If it's only showing up on your iPad then that could mean 2FA is only enabled on your iPad.
