Since today I`m having some trouble with the adgroup performance report download.
To be more precise when requesting the columns below I get an "Invalid Column_1" for the labelIds attribute
"Date", "CampaignId", "AdGroupId", "CampaignName", "AdGroupName",
"AdGroupStatus", "CampaignStatus", "Clicks", "Cost", "Impressions",
"SearchImpressionShare", "Device", "CustomerDescriptiveName",
"AveragePosition", "VideoViews", "LabelIds"
This happens randomly on some accounts so I`m not able to find a pattern between the accounts. A sample response after the xml parsing for that attribute is: "InvalidColumn_1": [576125964,576125976,576126204,576126219,576126234,971258273] (the serialized label ids)
