I emailed support and here is the reply I got...there is a known issue.
Thanks for getting in touch, we're very sorry about this! There are a few issues with the Search Ads feature at this time, our engineers are working hard to get this cleared up.
We've received some reports that Search Ad campaigns did not run on October 10th and 11th. We are reviewing this matter and hope to get these campaigns starting very soon.
Please note: if your Ads are not displayed, fees will not be added to your bill. Search Ad fees are based upon the impressions you serve; if you didn't serve impressions, you will not incur fees.
We apologize for any confusion or frustration this may be causing you and we hope to resolve this matter as soon as possible. Please let me know if there is anything I can do to help in the meantime.
