I have a number of datasets that are published to Power BI service. When I published these from Power BI Desktop, I was able to enable period refresh.

This morning however, the periodic refresh failed with a 403 Authentication Failed error. I can't enter the Personal Access Token into the PBI service to re-enable periodic refresh.

The Personal Access Token is still valid as the PBI Desktop application can still access our data.

It's not clear to me how I should enter the Personal Access Token into the PBI Service. I can select Basic, Key or OAuth2 verification. But none of those will accept the Personal Access Token as valid credential.
