DM has a new phone, she's very pleased with it.
The very nice man in the shop told her all her settings would "follow her over" to her new phone. Her settings have not followed her over 
It now appears that DM has no less than three different FB accounts. I assumed she was changing profile pictures, turns out she was just logged into different accounts of the same name. This also explains her indignation that people have not replied to her messages.
She does not know her AppleID and appears to have locked it to DSDads fingerprint- sadly he died two years ago so is not really being much help.
Any requests for passwords are met with blank looks, as if it's an utterly outlandish thing to request.
