Jira team-managed project permissions dictate if and how you can access a project -- whether as an administrator, member or viewer.
In order to see the issues and time records for a team-managed project, you need to be a member of the project's board. You can go to the Project Settings of the project, and then select Access in the sidebar to see who has access to the project and/or grant access to it.
For more information about team-managed projects, see Atlassian's documentation.
