Unable to connect Power BI Desktop to Dynamics 365 after upgrade to v9

[barbforsman]

We recently upgraded our D365 to v9.  I can connect a new Power BI report to this environment using = OData.Feed("https://nebraskalink1.api.crm.dynamics.com/api/data/v9.0/")

but I am unable to update to this connection on my current reports. 

Do I have to start from scratch again, or is there a way to update the connection I already have?

Error when trying to update source

@barbforsman,

Clear permissions in data source settings and try the latest version of Power BI Desktop.

I ended up opening a ticket with Microsoft Support.  The new API model for v9 to use is

= OData.Feed("https://d365_instance.api.crm3.dynamics.com/api/data/v9.0", null, [Implementation="2.0"])

This connected successfully.  Unfortunately once I connected I ran into this issue

(400) Bad Request. (Number of calculated fields in query exceeded maximum limit of 10.)

I ended up rebuilding my report from scratch.
