This app is no longer shared with you
Just setup family sharing with my wife. Went to download one of the apps she purchased. I can see the list of her purchases, but when I download the app and try to open it says: "This app is no longer shared with you". We checked that "Share my purchases" is turned on for her. I tried restarting the phone, sign out and back in for App Store, restoring the phone and all for nothing. More than that, the app I'm trying to download was bought after family sharing was turned off. So it went through my credit card and Apple ID. My wife has the same problem downloading apps that I bought.
What can I do to resolve this?
