You’d have thought twelve months would have been enough time for you to change “iOS 11” to “iOS 12” in this template.

If you are on Beta 12, you will notice Beta 12 and GM share the same build, with the exception of Beta 12 having an "a" at the end. As such, GM is Beta 12, and if you are running Beta 12, you will not see an update, since you're running the same version of iOS 12 already.

Well .. that is not true ..

Incorrect. I am running beta 12 and I have an update. The GM removes a the feedback app as well as some other background stuff. Beta 12 is NOT the GM

You sound like my dad. He formats and reinstalls his OS once a month.

Unlike your dad I want my apple gear to be in top shape; I format and reinstall 3 times a day!
