I can't connect to family apple news account
I can't connect to a new family apple news account on my iphone or macbook pro. Following advice online, I updated the iOs and MacOs, but still can't seem to connect - it wants me to pay again. The point of purchasing a family account is so that we don't need to jump through hoops (or pay) for two subscriptions. Surely there is a way to do this, fairly quickly. Explanation would be much appreciated.
iPhone X, iOS 13
