My ads were up and running for about a week. Both the tests ads on my device and the real ads on other devices were showing up. Now, all of a sudden, all of the ads have disappeared. This includes test ads. I am still getting ad requests according to the dashboard, but eCPM has fallen to zero, match rate has fallen to 0%, and impressions have dropped to zero. This happened without any changes happening to the code. I have not committed any policy violations; at least, AdMob has not alerted me to any. What is going wrong?
