Why doesn't the parent see the tuition due on the App?
If you do not see any tuition due make sure there is any to be paid in Financial Management → Tuition Due by filtering by its name.
In case the Minor has multiple guardians, make sure the order is in the name of the Guardian who wants to see the Fees Payable. In order for all guardians to see the Minor's Fees Payable, head the order to the Minor.
