Family member being asked to pay again for app I already purchased and shared with her? I set up family sharing, my family members are able to locate the apps in their iphones and download them, but if they are not FREE apps, and I already paid for them, they are being asked to subscribe and pay again?

Any help is much appreciated. Thanks
If Family Sharing is enabled, they should be able to re-download paid apps at no additional cost by tapping App Store > Purchased. 

If they are on separate Apple ID's linked through Family Sharing they need to choose your account from the top right corner of the Purchased section in App Store. Then they should be able to download the paid app(s) at no additional cost.
