If I sign up for a subscription, will all the members of my groups receive the subscription benefits?

Subscriptions follow the account holder, not the group, but members of the group will see some of the benefits. For instance, non-subscribers will be able to view longer videos uploaded by subscribers but those non-subscribers will not be able to post longer videos themselves unless they subscribe. Additionally, Apple App Store subscriptions will be shareable through Family Sharing, so if your partner or another member of your family wants to share the benefits, they can!
