I am stuck at this point when I click on the Refresh button. Looks like there is a problem in September 2021 update, I've downgraded to August and it's working fine.
Hello!
For me it is working: Versão: 2.98.1004.0 64-bit (outubro de 2021) - Brazilian Portuguese.
If you didn't already, try and uninstall completelly Power BI from your machine and do a frsh install. (It is unknown territory, so the difference can be in the details).
I was running rolled back to August. I then uninstalled it and installed 2.98.1004.0 64-bit .
The problem was fixed right away!
Good luck. It was really annoying.
