Issue Level Security is turned off on our project, but when a Customer logs in to the portal to try and view a request created by another Customer they are denied with an error that says 'No Access - You do not have permission to view this request.' I've tried to open up whatever permissions might be necessary for them to view the request but they still get this error.
The goal here is to let any customer revisit resolved issues so that they can be re-opened with a comment. If they cannot get access to requests made by other customers it will seriously disrupt our planned workflow.
How do I let my customers view all the requests on the portal regardless of who created the request?
