If you are not seeing any shifts on your schedule, here are a couple of things to check:
Check that you are in the correct facility. If you work at multiple facilities, it is possible you are looking at a facility you have no shifts for. Tap the arrow next to the facility name in the upper left and select the facility you want to look at.
Check with your manager that they have you on the schedule. It is possible your manager has invited you to start using Covr without adding you to the schedule yet.
Check that you are on the My Shifts tab and not the Open Shifts tab.
The Covr Employee app only shows your upcoming shifts. To see shifts you've already worked, log in to the Covr Employee website at https://employee.covrhub.com/ with the same email and password.
