Just came across this documentation which says that Google ads is going to allow third headline in the expanded text ads.
But it is not clear if it will be a new Ad type or the existing ad types (EXPANDED_TEXT_AD) ? There no documentation available for the API users for this feature, this sound like an important feature, we wanted to be ready when it starts to roll out in August.
Can you please tell the ad type id used for these kind of expanded text ads ?
