Example of the issue:
My child cannot mark the homework as 'Handed in', only that they have 'Done' it.
Is there a way of rectifying this or is it for the teachers to mark as handed in?
My child has tried on both their mobile app and using a desktop computer, but without success.
Your child has done what precisely what is expected of them as a student Milk user. It is now up to your child's teacher to mark the homework as 'Received' in accordance with your schools homework policy (every school is different). If your child's teachers do not mark the homework as received, your daughter only needs to tend to the incomplete homework tasks within the 'To do' tab of their Milk page.
