The first exemple which comes to my mind is Infuse, which has a separate "Infuse Pro" version which works with family sharing.
I had gotten the in-app purchase and a few month later when I asked them about family sharing they were actually kind enough to give me a voucher for other version based on proving I had paid for the in-app.
Hmm.
It isn't an app I use to be honest but sounds like a good system for the customers point of view. Good of the developer to go to the trouble.
To be clear it is $9.99 for only 1 Apple TV in my house? So if I logon with the same iTunes Account on multiple Apple TV's it will still only work on 1 Apple TV? Also, will this be 1 purchase for iOS and 1 purchase for tvOS or does it only work on iOS. Pretty confused here. Also, I have purchased a number of games for my grandkids but the ones where you can hardly play because all of the in app purchases are terrible.
They need to price it so you can just buy the app and enjoy playing. In App purchase is terrible and needs to end.
Its a universal app I believe so it will work across all of your devices, assuming you are signed in using the same ID.
