Q: What do you do when apple support pages are wrong or out of date?

I'm doing my best to fix my icloud keychain problems using apple's support pages. However, like so many times in the past, these pages are either out of date, just plain wrong or ambiguous.

So ... after much hair pulling, I've learned from the doc " Get help using iCloud Keychain" that I need to turn off icloud keychain on my three devices. But the instructions fail to say how I'm supposed to do this. Nor does it provide a link to any such instructions.

Then ... after more hair pulling, I finally found this page "Frequently asked questions about iCloud Keychain” that supposedly explains how to remove iCloud keychain. Not sure if that’s the same thing, but when I try it, I find that the “allow approving security code”  doesn’t exist. Which is surprising since the page was last modified  3/21/15. You’d think they would have caught that.

The only satisfaction I’ve had during this CF is leaving negative comments on the survey they keep asking me to fill out.

Please … does an explanation of how to “Turn Off iCloud Keychain” anywhere on the apple support pages? I've got to get some work done today.
