Screen Time: what is the difference between Daily Usage and Usage.

Hi there,

Hoping someone can help me please.

I am trying to work out the daily usage for my daughters phone.

When I look at the weekly usage the heading is 'Usage' and it gives me a number. However the is a greyed out bit at the top of the bar graph. When I click on the day again the heading changes to Daily Usage and gives me a much greater figure.

It also says her average is higher than her usage. How is that possible?

Can someone please explain this to me.

thanks
