We've recently needed to change the permissions of our PowerBi reporting which utilises a web part API to "GET" our Business Glossaries and other various Govern properties that we'd like to report on.
The function itself works correctly and we've updated all of the API keys to reflect current admin users that are responsible for updating the report. We know this works as when we Refresh the data via the PowerBI desktop application via an Anonymous permission connection, we get a successful run.
The issue we're currently experiencing is when we come to Publishing our report to our app.powerbi area - it doesn't accept our credentials and this stops us applying an automatic refresh schedule.
Any advice or guidance would be greatly appreciated.
