In app purchase didn't work
we have set up family sharing on my sons phone and it works well. Today made an in app purchase from his iphone and his Apple ID with a gift card. I was prompted to approve the purchase and the cost for the purchase was taken off the gift card associated with his apple ID. However, the purchase does not show up on his phone. What we purchased, he has not received yet. He made the same in app purchase recently and it worked previously. Any ideas?
