icloud family storage not showing on one phone
I have an iCloud 2Tb Family Plan shared between myself, my wife, my son, and my daughter. The family sharing works for my wife and son, but it does not register on my daughter's phone. The other iCloud family plan features do work on her phone, but her phone still shows the default 5GB storage, which is full. It says to upgrade I would be purchasing a plan. If I do that would Apple recognize that I'm really just bringing that phone into line with the plan that it should be on and that I'm otherwise paying for (and not charge me twice)? If not, how do I get my daughter's phone to recognize that it is on our iCloud family storage? I cannot find anywhere in OS12 to send an invitation.
