Can I share my subscription via the Family Sharing feature?
According to Apple policies, in-app purchases cannot be shared with family members. See here to learn more about what types of content you can share with your family using purchase sharing.
However, if you have an active subscription, you can use the app on different iOS devices. By doing so, you can use the same account for multiple people. If that works for you, please follow these steps:
Make sure you have an active subscription and that you are using the same Apple ID that you purchased the application with.
Download and open the app.
Tap on the 'Get started' button and enter your information as if you’re a new user.
When you get to the payment screen, click on the 'Restore purchase' button (at the bottom of the payment screen) to be able to get back into your account and continue using your subscription plan.
