New Purview Portal - Missing Sections

Hi

We've recently upgraded to the enterprise tier and started using the new portal.

However, we're missing some sections within the Data Catalog solution. The entire Data Management menu/section is missing, so we can't access Business domains or Data products (using a Purview admin user).

Here's what we're seeing:

We've granted the tenant-level data governance admin role to our Purview admin user, but we're still unable to access the Data Catalog "Roles and permissions" page.

We've followed all of the instructions described in the link below without any success:

Has anyone encountered this before? Some assistance or guidance would be appreciated.
