Ads stopped appearing yesterday morning. After I investigated, I discovered the the Google ads.txt line was missing from the ads.txt file. I have no idea who removed it as I am the only one who works on my website, and I know that I did not remove it. I've always been very careful to keep it at the very top of the ads.txt file. I never received a notification on my dashboard that the file was missing. The correct file was uploaded 24 hours ago, and still no ads are appearing. Does anyone know how long it takes for ads to start reappearing?
Also, I am wondering why I didn't receive a notification on the Google dashboard.
