When you say “family shared account” do you mean you have one Apple ID that is shared between 2 or more people, or you each have individual accounts that are grouped with Apple’s Family Sharing feature?
If you mean you have multiple users on one Apple ID that is not a recommended practice. If you are not doing this, and have Family Sharing, ignore the rest of this post.
Apple IDs are personal; they shouldn’t be shared any more than you would share a toothbrush. If you share an Apple ID with someone else many bad things will happen. Each user should have their own Apple ID, then you can create Family Sharing→What is Family Sharing? - Apple Support. That way you can share what you want to share and not share what you don’t want to share.
It is OK to share an Apple ID among devices used by one person, such as an iPhone, an iPad and a Mac; in fact, it is a very useful thing to do. But not between devices used by different people.
