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.
Agree with all the comments above. Disappointing. This is my first real big bug working with PBI Desktop (for over 2 years now). Never had to revert back to a different version and stay on that version to keep it working. Yikes.
