Many of our clients have made custom roles and/or changed the capabilities of the Tenant admin role so that these users can not MAKE reports, just read the reports that are provided.

In Moodle 3.11 MWP there used to be two capabilities that regulated if a user was able to:

• READ custom reports

• EDIT custom reports

In MWP 4.X the capability to just READ reports seems to be missing. Either you can EDIT and READ reports or you can not see any reports that were suplied (either in the Shared space or in a tenant), just a empty report page. 

A workaround could have been to add the role to the Audience to the reports. Sadly the role "Tenant administrator" seems to be missing in the list of roles to add to the Audience of a report.
