I'm trying to add external clients to a Jira project, but they are unable to view the Jira board. I have created their own group and assigned them to a Developer role and they have permission to browse projects, as well as other permissions to create, assign, transition, comment, etc. I have shared the board filter with each of these users as well. However, the user is still unable to see the board. The user is able to see issues, though. I'm also seeing "failed to retrieve product data." Any idea what's going on here and what I need to do to get them access to the board?
