Cannot access reports in App - No permissions to underlying dataset

Hi amarcucio thanks for your sugestion. I can confirm this works as a workaround but it's not really a long term solution as we don't want to be giving everyone access to the underlying dataset for security reasons.

We debugged this with support from Microsoft and they recommended we try unpublishing the app completely and then try republishing. We could not do this in our organisation as it would create a new URL for the app. So instead as a permanent fix we moved all the Power BI objects over to a new workspace and that resolved the issue.

Also, we now had a 2nd seperate workspace in our organisation that is experiencing this issue so it definitely is not an isolated case with the new App experience.
