   We are aware of an issue where Wunderkind ad tags are being intermittently disabled across multiple publisher sites due to a third-party ad serving platform flagging our tags. This is causing inconsistent ad delivery for affected publishers. We received information on solutions to implement today and we took the following action: We submitted a certification request with the third-party platform, which may take up to 3 business days for approval We deployed update to address the flagged issue Our team is prioritizing these two fixes before evaluating additional remediation steps Client action: In the interim, clients should continue to manually re-enable their ad tags when they are disabled. Our team will proactively monitor traffic each morning until this is fully resolved. Next update: We will provide another update on Friday April 17th or sooner if the certification is approved.

   The certification request submitted to the third-party platform is still in progress and under review. We have not observed any major performance dips over the last 3 days, however, some sites remain pending re-launch. The update we deployed on April 14th has not introduced any regressions and eliminates one of the flagged variables from the equation. Client action: In the interim, clients should continue to manually re-enable their ad tags when they are disabled. Our team will proactively monitor traffic each morning until this is fully resolved. Next update: We will provide another update once the certification decision is received or on Monday, April 20th.
