Does iOS8 Family Sharing allow to share In-App Purchases? When using the new iOS8 Family Sharing feature, I can download the apps purchased by the other group members of my family. 

If these apps use In-App Purchases, and one of the family members has already purchased some content, e.g. a new guitar amp for the JamUp Pro XT guitar/bass amp simulator, do other members of the family get to benefit from these In-App Purchases? Or does every family member have to purchase the same content in the app again?
In App purchases are not shared in Family sharing and its clearly given in apple website. But what we can do is log in to iTunes &amp; App store using the ID which was used to buy the in app purchases without having to change the primary ID of the device and still enjoy the in app purchases
