Google has replaced the Google AdSense "i" button on the AdSense ads with "Ad Choices." We knew this was coming and now it has happened.
When I go to a page with an AdSense ad, it loads the ad and shows AdChoices in the top right.
Then it removes the word AdChoices and shows just the logo.
You can see the word again by hovering your mouse cursor over the ad or logo.
Clicking on the AdChoices logo takes you to the What are Ads by Google? and then lets you report an issue at the bottom of the page.
So do not be surprised when you see the "i" replaced by "AdChoices" - it was expected.
