ios app family sharing
I downloaded a free dictionary from the App Store for my iPhone. I liked it so I bought the premium version (an in-app purchase). I have app sharing set up with my wife but when we downloaded the app on her iPhone (it was registered as purchased under my name on her iPhone), she got the free version, not the paid for unlocked premium version.
Does this mean premium versions bought as an in-app purchase cannot be shared between family members? Or have I done it wrong?
We both have the iPhone 11 Pro on IOS 13.5.1
Thank you for your help.
