Dynamics 365 OData error with Power BI desktop

[BrentMcA]

Hi, I am trying to connect Power BI desktop to Dynamics 365 Online. 

After putting in the correct credentials, it starts to load the metadata then fails with this message:

"OData: The feed's metadata document appears to be invalid"

I am using the OData endpoint URL that I copied from the Instance Web API section in D365 Settings eg:  https://crmxxxxx.api.crm.dynamics.com/api/data/v9.0/.

This is a clean install of Dynamics 365 so there is no customisation of the schema.

I can return the metadata in a browser and nothing obvious stands out.

I have successfully connected to a version 8 instance of Dynamics 365 so I know that I have the right steps.

Is there a known issue with Power BI desktop (latest version) and the July 2017 release of Dynamics 365?

Regards
