I did some work in a pbix file after downloading the Nov update but never published the work i did to power bi. I could never re-open this pbix file becuase it was corrupted. I understand that there was a bug in this nov update and i should revert back to an earlier verision which i did. Now all of the dashboards that have visuals from this report are showing blank and saying the following
'The report shown in this tile doesn't exist or you don't have permission to view it'
This is a major issue as i have many visuals on many dashbaords that link to the reports made in this pbix file!
