It's unclear if this feature is currently supported. Can I create a feed, attach it to a display campaign, and refer to the feed in Responsive Display Ad's short headline as
"{DataSet.Attribute} - this is a great ad"
According to the community, this is not supported for Display network responsive ads.
However, the documentation says it's possible. Also you can actually save a responsive ad from
adwords.com's web application, it doesn't throw an error.
So what's the verdict on this? Is it supported or not?
