Howabout YSM now.... my YSM stats haven't updated since 12:30 AM EST 7/27 ...
We apologize for any confusion regarding your Account not reporting your most recent activity, we are happy to explain.
Currently we are having a reporting delay that is preventing the Impressions and Clicks from being displayed in the Accounts. Your Ads are still displaying online and your Account Balance on the Administration Tab is still being updated as normal. We appreciate your patience while our engineers are working to resolve this issue as quickly as possible.
