So I've come across this problem, but can't seem to find a solution. The last post here was six months ago. Is there a workaround? I tried changing the API to 14 but got a data source error instead.
The work-around I used is to set the regionalization on my sharepoint consistent with the one I'm using in Power BI, since my hunch is that the API is having issues when having different date formats (ie. mm/dd/yyyy versus dd/mm/yyyy)... eventual timezone shift you still can compensate in your power query logic.
I still don't understand why the Power BI support team needs votes to resolve bugs that harm global implementations.
