Content Impression Share - Video - Adgroup level
I'm trying to extract the Adwords Content Impression Share at the Adgroup level, but no data is returned for Video campaigns (TrueView Video Discovery ads).
When trying to use "Available impressions", it also returns no data for Video campaigns, but it does return data for Search.
Is there a particular reason for the lack of data of IS on Adgroup level? If I want to include IS data at adgroup level, it doesn't seem to be any option via Supermetrics. Is there any workaround available?
Thanks in advance,
