Family sharing - child's password

Hi, my daughter has forgotten her password for her iCloud account. She is set up on our family sharing so it is linked to our account if she purchases anything via the app store.

I have been trying to reset her password via iforgot but nothing has happened (its been a week), I finally speak to someone at Apple yesterday who said the reset request would be cancelled if she used her phone on any apps she had purchased using her apple id in the 24 hours following a request.

Therefore, she must wait 24 hours for it to be reset until she could use her phone / those apps again.

However, she then hung up on me before I finish my question - I am not clear if that means she can not use her phone for 24 hours or all of us who use our (parents) apple id for making purchases can not use our phones for 24 hours - can anyone help? Thanks
