Bjorn is using a third-party tag for their upcoming display campaign, but the third-party tag indicates it is “Unrecognized” in Amazon DSP. How would you help them troubleshoot this issue?

The correct answer is Check to see if the creative macro is being used or is invalid because the "Unrecognized" status for a third-party tag in Amazon DSP often indicates that there is an issue with the creative macro, which is part of the tag used to track ad performance and data. Creative macros are short commands embedded in the ad's tracking URL, and if the macro is either incorrectly formatted or invalid, it can cause the tag to be unrecognized by Amazon DSP. Troubleshooting by ensuring the correct use of macros and verifying their validity is essential to resolve this issue. While checking the Amazon Ad Tag or considering a server-to-server integration could also be relevant in different scenarios, the direct cause in this case is most likely related to the use or invalidity of the creative macro.
