Q: Why does the two step authentication not work with all downloads of newest operating system?
I was just informed that even though I have the newest operation system updates that the two step authentication does not update at same time. Does anyone have more information regarding this issue?

It is not yet available to me either. It is being "rolled out gradually." See the quote below from Two-factor authentication for Apple ID - Apple Support
Starting this fall, two-factor authentication will be rolled out gradually to users who meet specific system requirements and other criteria designed to ensure the best possible user experience. We’ll increase availability over time until we can offer the feature to everyone. You can learn more and see if two-factor authentication is available for your Apple ID.
Until two-factor authentication becomes available to you, you can use two-step verification: Frequently asked questions about two-step verification for Apple ID - Apple Support
