Hi
What did you mean about the "one of the Google analytics reports has a filter and in that filter it has a REGEX = 'www.gov'."? Did you add this filter on the Google Analystics account level filter? Where did you find "the #s add up to what is in power BI"?
When we connect to Google Analytics in desktop, the data is retrieved rely on Google Analytics Core Reporting API. You can see: Third-party service: Google Analytics connector for Power BI Desktop. And in Power BI Service, it's based on Google Analytics content pack for Power BI. Based on my test, whether I add a filter or not, when connect to the Google Analytics in Power BI Desktop and Power BI Service, I do not see the #s.
So in your scenario, would you please share detail steps for us to reproduce the issue?
