This has happened on multiple fields on different entities now, where I create a new field and the Power BI Dataverse connector doesn't pull it in during Power Query.
I create a new field on an entity (D365 Settings - Customizations - Customize the System - navigate to the User entity - open Fields view - go through new field creation dialog - save changes - publish changes) but when I open Power Query Power BI Desktop, the new field doesn't show up when I use the Dataverse connector. If I use the older OData feed connector, I can find the field, but I would prefer using the Dataverse connector since it is SO much faster and easier to use.
Below is a screenshot of the created field on the User entity - is there some additional change or toggle or refresh required for the Dataverse connector to see this new field?
