Hi there,
I've experienced a recent bug with AdWords cost data retrieved via the GA Core API over the past few days only (since Monday 9/2/15).
What is strange is that I can see the correct cost data reported in the GA UI whereas now the core API is only reporting non-AdWords cost data (BingAds cost data that only)
Here’s a sample query that doesn’t report the correct data (only BingAds cost data)
Many thanks in advance,
