Hello, With August'22 version I have an issue when I try to apply changes or discard them. Seems not working neither:
Same issue with blipblipblue
I have multiple reports using by Power BI desktop and one of .pbix file suddenly popup pending changes once I opened file by PBI desktop August 2022 (MS Store) version and it's unable to remove the popup by refreshing data and queries while the other .pbix files don't have any issues.
Lastly I tried to clear all caches and restart Power BI desktop, could eliminate this issue.
