Minecraft Not Working with Family Share?

Son downloaded Minecraft but others on family share were still prompted to purchase. I followed solutions that helped make sure family share, purchases etc. were set up but was still prompted to pay.

Solution: After giving up and requesting a refund I went to purchase on organizer account. On the last step before paying a message popped up saying ‘someone in your family share already purchased this item. Download for free.’ What? Lol I’m happy but my brain hurts. I guess just go through with the purchase of the same app and it will recognize family purchase and allow you to download for free.
