DD has been getting grief from a girl at school over half term, which continued today at school so DD has now blocked this girl on WhatsApp. I’ve checked DD’s phone and this girl viewed DD’s status an hour ago 
I’m wondering if this is purely due to the timings (as the status was updated and available for girl to view before she was blocked) or if even though the girl is blocked, DD will still have to make her status’ invisible to girl every time she updates it? So,
8am - DD updated status
4pm - DD blocked girl
9pm - girl viewed DD’s status
Any ideas?
