Family sharing
Hi
I had a apple music account,Â
I decided to change my individual (1 year) subscription to family sharing. When i tried to add family member, it asked me to  add a payment method to my apple id.
I always charge my account with gift cards and my payment method is Non.
Also i have no choice to take a debit card.
Can you help me How can i use family sharing for my apple music ?!
Thanks
