The Timesheets Dashboard card has a filter for "Approval Status" called "Not submitted". This filter does not work
Speaking to customer support it isn't a bug. It hasn't been developed.
Only the other approval statuses "Approved" "Pending Approval" "Changes requested" have been developed.
So the card has a filter option, but there's no function behind that filter option to make it work.
When my team submit their timesheets the only way to check who hasn't submitted yet is to manually compare the list of those who have submitted against a list of all employees, and pull out the missing people. Or go into each individual timesheet and look if it is submitted. If i grow a team of 50-60 employees, this becomes a time consuming and tedious task.
