For the last few weeks, I have been unable to connect to Google Analytics. I thought it might be something wrong with my query as the error message is below, but it seems to be broken on all the queries I have to it. I tried starting a new source to GA and it is actually giving the same error in the Navigator window. No other information is shown there. I am on the Nov 2018 version of Power BI.
