When family member goes to download sharable app, appears to have to pay again.

I purchased an app and have confirmed that the app is shareable and have confirmed that the family member is on my Family plan and that I have sharing purchases and subscriptions turned on for her, but when she goes to download the app, it appears as though she will have to purchase it again. I've also tried sharing the app from my iPhone via the downloaded app—same thing.

Is this as simple as (but unintuitive for Apple) her clicking on the $6.99 button and it then indicating it is a free download, or clicking and paying and then going to request a refund from Apple?
