Has this happened to anyone else? I created an ad unit for one of the more well known fashion brands in the world. And it lives on a page for this brand. As I started looking at performance the last 30 days, I noticed that this ad unit has just disappeared from the "My Ads" area. Every other ad unit I can still find. When I go to my page and check the source code, ads are appearing and referencing this ad unit. So I ran a performance report for the last 60 days and I see where impressions essentially just ended for this ad unit almost a month ago. So AdSense is saying there have been very impressions lately - which is impossible.
I just created a new ad unit and re-tagged the appropriate page. My question is how did this ad unit disappear? Anyone else experience this before? Never a message from AdSense. Odd + it cost me lost earnings.
