I have 10 project on my jira software & 2 users user A & B user a has right to access & view all the projects But i want user B only can access & view one project. User B should not be able to access & view remaining project under all projects
you will need to check the permission scheme in place. Right now the browse permission seems to be granted tobe a group both users are a member of / or directly to the users.
