yesterday around 5pm in the evening I received a warning message from Google this was the message

"Earnings at risk - One or more of your ads.txt files doesn't contain your AdSense publisher ID. Fix this now to avoid severe impact to
your revenue."

then I simply went to my AdSense dashboard, clicked on Action (beside the warning note) then it took me to a page where is saw something like google.com,Direct pub-00000000000000, I copied it,(although my publisher ID was already there) then I copied the code and pasted it on my custom adx. Google said if you have already done this wait for 24hrs for the system to change, I have waited but my adds are not back to my blog, did I do anything wrong?
