After investigating some issues with the "AD_REQUESTS" field, we discovered that the field had been deprecated by Google on July 8, 2019 and this is leading to the field not behaving properly.
So on June 24th, 2020 this field will be marked as deprecated and will no longer return data, please remove it from your reporting:
- Ad Requests
- Ad request CTR
At this time, there is no replacement. We will need to update our connector to support the Ad Exchange Historical reports so we can add AD_EXCHANGE_AD_REQUESTS. We are taking the early steps now needed to support the Ad Exchange Historical reports, but we cannot say when we will have this feature fully added.
For Data Studio users - You will need to refresh your data source to get the updated field list.
