You are missing specific video campaign data in your campaign_history, ad_group_history, or other history tables. What is causing this?
Connector: Google Ads
Video Campaigns are not supported by the Google Ads API. This is outlined in our docs:
NOTE: The connector cannot sync video campaign data for metadata tables because the Google AdWords API does not support video campaigns. Some data from video campaigns can be collected by creating a custom Video Performance report.
The workaround is to create a Video Performance Report, as mentioned. But this will not allow you to sync specific metadata fields found in the history tables, due to the limitation of the Google Adwords API.
