Hi @hwz! Thanks for the quick response. Not using twurl, but here are the request parameters w/ account and campaign IDs: (if campaign IDs should not be shared publicly let me know)
{"method":"GET","endpoint":"insights/accounts/18ce53vvrko","args":{"audience_value":"2bsws","audience_type":"CAMPAIGN","interaction_type":"IMPRESSION"}}:
^— this retrieves full information with no empty arrays, values for all insights as expected
{"method":"GET","endpoint":"insights/accounts/18ce53vvrko","args":{"audience_value":"2bsws","audience_type":"CAMPAIGN","interaction_type":"CONVERSION"}}:
^— this has several empty arrays (for Education, Marital Status, Occupation, for example)
Another campaign ID with similar results: 2bsw6
Thanks for your help!
