Unable to filter AdWords data by campaign in DataStudio
I'm having real trouble filtering my AdWords data by campaign name in DataStudio.
I want to create a filter to split by campaigns into Branded, Generic and Brand Products, and these are denoted within the campaign name. However when i attempt to filter (either using 'contains' or a RegEx) the report either returns a system error or no data.
Any help on this would be great,
