Hi team,
To address the 'Ad contains an unidentifiable vendor' error, we included the 'Vendor technologies' parameter when uploading creatives for Google review. Google displayed this parameter as follows upon successful review. However, once the creative started receiving impressions, the value of the 'Vendor technologies' parameter changed to None. This has caused an increase in the 'Ad contains an unidentifiable vendor' errors that were originally decreasing. We are certain that this change did not originate from our end. Could you please investigate if there is an internal mechanism within Google that modifies uploaded creatives? Additionally, we would appreciate guidance on how to resolve this issue. Thank you.
This issue is very important to us because 'Ad contains an unidentifiable vendor' affects Google bidding QPS. Thank you once again.
