I've set up Family sharing, and have 2TB of storage (the current maximum). I also pay for my wife's 50GB of storage. I want to migrate that over to use the new 200GB i've allocated to her out of my 2TB total.
I am sharing my storage plan with her and the screen says "Family members with a paid storage plan will be able to choose if they want to share your plan."
I can't see how to do that on her Mac however.
I've looked under
iCloud Drive options, etc and there is nowhere I can see where I could migrate her existing 50GB subscription to the Family storage.
If I go to
Manage and then
Change Storage Plan... there is no option to migrate to the family sharing.
How do I do this? Specifically how do I do this in such as way as the 10GB already in her iCloud storage is not nuked.
