Another excellent post, Don. Thank you for finding that other thread. I had not seen it myself.
I think that Google's wording is what was tricky:
make sure to authorize any sites where you display ads by visiting your account settings
And this quote from Google by David:
Site authorization is an optional feature that lets you authorize specific URLs to use your Google ad code. URLs that you don't include in the list of authorized sites will still show ads and report clicks and page views, but you won't generate earnings from them. Learn more about choosing if this feature is right for you.
Mary of Front Porch Ideas had an excellent answer:
We have experienced the same message on our Adsense account. I was able to ask someone at Google what we should do and here is her reply:
"You should only authorize sites that you own and operate. You do not need
to authorize your ads on sites like google.com"
I hope this helps. I wish the message would go away but at least we know we don't need to pay attention to it any longer.

Shambunath and Caroline showed that not allowing SBIAPS preserves you from clicking on your own ads accidentally.
Nowadays, my message in Adsense has a Dismiss button. Even though I dismissed it over the weekend, I did see it again and have dismissed it again. I am not seeing it in my Adsense account now.
How to see your verified list of sites? I had to go back through messages to work how to find this so here's the path I found as of today:
* Open the left navigation by clicking on the menu button (three lines top left).
* Click: Home > Settings > My Sites > Overview
[Edit: I meant to add that maybe I'm not seeing the warning in my Adsense account because I have not yet previewed a page today. I expect to this evening, so I'll see if that revives the message.]
