icloud sharing

Have you tried signing out of iCloud, restarting, and then signing back in to see if that updates the storage?

Did you do the steps in the article below?

Family Sharing - Share an iCloud storage plan with your family.    

I currently have the 200gB and I purposely don’t share with my family because it will just make them more lazy. I already have to be the one to delete all the blurry pics.. and accidental pics.. so I am betting there is something specific you must do before the sharing kicks in. You probably have to allow it somehow… probably in the iCloud setting on phone or iPad.

ok.. here is where you would need to press a button for the sharing to happen.
