We are facing issues with Power BI response today. Its either very slow or not loading the data at all.
Many users have complained over last couple of hours.
Where is your Power BI tenant located? There is a update in Power BI service currently.
I would suggest you test again to see if the same issue still occurs.

We have also been experiencing this issue since last week. Our reports are taking forever to load (screen shot below is of a page that has been stuck at "Almost done" for 20+ minutes). I tried refreshing manually, and while that supposedly succeeds, the reports are still not loading. The tenant is located at West Central US (MSIT).
