Hi,
Thank you for contacting the Mobile Ads SDK Support team.
I'm deleting the thread from the forum as it consists of PII information.
I have executed our Google Sample project with the provided information but unfortunately, I have been unable to load the ads on my end. It has come to my attention that the error message "no fill" is being displayed in conjunction with your IDs.
The Error code 3, no fill error means that the ad request was successful, but no ad was returned due to lack of ad inventory. You may check this AdMob Error Codes & Logs for more information on different kinds of errors. This is more of an Ad serving concern rather than anything specific to the code implementation of the Mobile Ads SDK. The next step for you would be to reach out to the Product support team for further assistance regarding the ad serving concern. The Product Support Team is well equipped to handle your concern effectively.
Find below your previous response with redacted information.
