Splunk Enterprise Security - permissions issue

[pc1234]

A user is unable to access investigations in Enterprise Security (version ES 7.1.1) on Splunk Cloud (Splunk 9.0.2) . When clicking on investigations from the main menu the message "You do not have permissions to access investigations" appears. The user is assigned the ESS Analyst role which includes the capability Manage-All-Investigations.  any ideas?

Thanks in advance.
