How do I share my iCloud storage with my family in iOS 11? I purchased a 200GB shareable (Family Sharing) iCloud storage plan but my family members can't see it on their devices. How do I fix this?
You have to back out of the iCloud Backup settings screen and navigate to the Family Sharing screen. From there you can tap on iCloud Storage under Subscriptions and Apps. And from there you can invite your family members to share your storage.
