Issue Summary

Admins cannot access, Move or Delete boards associated with private team-managed projects to which they have no access.

Steps to Reproduce

1. As a non-admin user create a team-managed Jira Software project and set its Access to private
2. As an admin user, go to your site's View all boards page e.g. https://YOUR_SITE_NAME.atlassian.net/jira/boards?page=2&sortKey=name&sortOrder=ASC
3. Observe that you can see that there is a private board belonging to the non-admin user, but you do not see its name or Location:
   
4. Select meatballs [...] Move and try to move the board to Your Profile:
   
5. Observe UI error

   We couldn't move this board

   Something went wrong. Try again.

Network response for this error:

{
    "errorMessages": [
        "Cannot assign next-gen boards to another project."
    ],
    "errors": {}
}

Expected Results

UI error message should reflect the actual blocker - you cannot move a team-managed board.

Also on the View all boards page, admins should be able to see the associated project, even if it is a private team-managed to which they don't have access. Note they can see the name of the project from the View all Projects page.

Actual Results

Unhelpful generic error message when trying to move a board associated with a private team-managed project.

Workaround

You can try and locate any team-managed projects on https://YOUR_SITE_NAME.atlassian.net/jira/projects where the Lead is the same person as the Admin of the board. Then click meatballs [...] > Project Settings and grant yourself access to the project:

It is not possible to search by Lead, however, so this is not a viable workaround if a site has a large amount of projects. If you cannot identify which team-managed project a private board is associated we recommend creating a Support Ticket with us make reference to this bug ticket
