Hi @RicardoCauduro ,

Maybe your account admin disabled automatic assignment of newly created workspace to your unity catalog's metastore. 
Ask you account admin to check if your workspace has been assigned to metastore. If it hasn't been assigned you won't be able to see anything related to UC at your worksapce.

Your admin can assign your workspace to metastore in following way:

1. As an account admin, go to the Azure Databricks account console.

2. Click Catalog.

3. Select your metastore.

4. On the Configuration tab, under Workspace assignment select your workspace and assign it to metastore.
