How Do i Hide in the portal my issue's from my customers

i Followed that guide but still everyone is able to see it, maybe i understand it not right how the settings are meant.

HI @Frank 

Go in the JSM project and see Customer permissions.

From Atlassian documentation:

Based on the option, set the 3rd option.

Currently, it’s not possible to disable the option to share a ticket.

In case you don’t want them to share the ticket with anyone, select the first option “Customers can search for other customers within their organization”. This is the best option because, since they are not in an organization, they won’t be able to share the ticket with anyone.

The second one “Customers can search for other customers within their organizations, or manually enter the email address of other customers within their project” will allow them to share the ticket with other customers from the project, but only if they add the entire email address.

The third option “​​Customers can search for other customers within their project or organizations” allows them to just type the name of the person they want to share the ticket (it will appear a drop-down with their names). The difference between this one and the second option is that on the second one they will have to add the entire email address of the person.

Permissions for your service project and Jira site

With this said, customers can only view tickets where they are the reporter, participants, or members of an organization that the ticket was shared with.
