We’ve reported couple of days back that Google by mistake sent rejected Ad requests alerts to some AdSense accounts (out account is also included in that) where Google AdSense Known Issues page mentioned no action is need to be taken from affected publishers ends, and today this page has been updated with Resolved message.
Below paragraph on the page reads about the update as
“Update (11am, August 31): The issue with our notification system has been resolved. If you’re still seeing an alert in your account that you have rejected ad requests, please follow the instructions in the Help Center article linked from that alert to resolve the issue. Thanks for your patience as we resolved this.”
I checked my AdSense account today and this alert cleared without me making any changes, I’ve waited for official update in AdSense Known issues page which now shows fixed to confirm and report.
If you’re still seeing this alert even after the fix claimed by Google to their notification system, here is help article to fix the rejected ad Requests your self (you’re required to login to your AdSense account to view this page).
