After checking the backend, I found the following notification:
"Because you haven't confirmed your PIN and/or telephone number, public service announcements (PSAs) will be displayed on your site. For more information, please refer to the 'Actions Required' box on the payment history page."
I had always thought that not verifying my information would only affect the disbursement time. After this incident, I realized that if you reach the payout threshold without confirming your information, Google AdSense content ads will display public service announcements instead, meaning you won't earn any additional revenue.
Therefore, it's important to verify your Google AdSense account as early as possible. This experience serves as a reminder for everyone.
