So I went onto the App Store today to download an app from another Apple ID which is linked with family sharing and couldn’t find the option to select the other Apple ID in the App Store. Family sharing is setup correctly on the iPad, I checked and it works fine on my iOS10 devices. I had the same experience on my iPhone, couldn’t find the setting to select the other Apple ID. Is Apple introducing changes to family sharing we don’t know about? Just wondering if anyone else experienced the same issue I have.
