Multiple users within our GCC tenant are reporting that the Microsoft Store auto-updated version of Power BI Desktop (April 2021 2.92.706.0) has broken connectivity to dataflows. They cannot refresh existing solutions with connections to dataflows (in Desktop) nor create a new query to connect to dataflows that they have access to (I've verified access).
I've had them sign out and in of Power BI Desktop, delete cached credentials from the Data Source Settings and re-enter credentials, uninstall and reinstall the April 2021 version, restart their computer, revoke cached credentials from the Windows Credential Manager, all with no luck.
The error is:
We couldn't authenticate with the credentials provided. Please try again.
Manually reverting back to the March 2021 version solved this issue for our users.
