In this trailhead step: https://trailhead.salesforce.com/content/learn/projects/connect-data-cloud-to-copilot-and-prompt-builder/bring-external-data-into-the-contact-page-layout?trail_id=unlock-your-data-with-data-cloud
I have successfully completed the "Enable Data Streams" section, adding the "AIPlusData" Data Bundle to my org. However, in the next section, each time I attempt to "Create New Ruleset" (under Identity Resolutions), the Primary DMO picklist is empty, and the dialog displays the error, "Mappings from Data Streams to the standard Cloud Information Model objects such as Individual and Contact Points are required."
This doesn't make sense, since the data bundle included the CRM Contact object and mappings to the Standard DMO objects, including Individual and each of the Contact Point objects. I reviewed the Data Stream mappings for the Contact Home DLO, and did note one warning for Contact Point Phone because the Formatted E164 Phone field wasn't mapped. I mapped it and refreshed the stream, but no change in the error message.
This is a new "Data Cloud and Einstein 1 Playground" created directly from this trail, today, with no other activity besides following the steps in this Trail.
for me it looks like the DMOs are still in the processing status which I assume is my issue
