My partner has a basic iCloud account (200GB storage). I have just bought the next level up and have invited them to share this new, larger space.
My Apple account shows that there are now two of us sharing my storage. But my partner's Apple storage makes no mention of their now being on family sharing. Instead it shows as still being what it always was (i.e. the 200GB they have always had).
I don't know what I need to do to give them access to my storage space?
