@ibimina I may not be testing this PR right but when I start my development server and navigate to /managerDashboard I am able to view the contents without first authenticating.

For testing purposes, I think it would be helpful to include Login and Logout links - no styling, just the links, so that we can properly test the guarding of managerDashboard access. 🙏🏾

@msarit redirect to landing page fixed, I will add the links to other page
