Users were blocked due to timesheets pending approval, however the calendar showed all weeks as reviewed (blue color).
Prevent Future Issues
In the User Form on the maintenance module:
- Add the roles "TimesheetNavigate" and "TimesheetApprove"
- Login with a user that enters time, add timesheet and send them for approval
- Login with the approver and verify that you've received those timesheets
- Check those days on the side calendar and confirm that they are showing in orange ("to review" status)
