I have created a family subscription to Apple Music. When I try setting up family sharing to use the subscription, I'm unable to proceed to the final step where I invite other family members. I've spent nearly two hours on the phone with Apple Accessibility; and as yet, they've not beenen able to find a solution. I am using the latest I O S on an iPhone 6. I would appreciate any help or suggestions; and I would also be curious about whether anyone else is experiencing the same issue.
