Based on the statement that "The organizer can review the item and make the purchase or decline the request right from their own iPhone, iPad, or iPod touch with iOS 8 or Mac with OS X Yosemite" implies Family Sharing cant be done with older device.

Regarding Family Sharing - Based on the statement that "The organizer can review the item and make the purchase or decline the request right from their own iPhone, iPad, or iPod touch with iOS 8 or Mac with OS X Yosemite" does this imply that Family Sharing can't be done if the Family Organizer has an older device? I have an older ipod that uses iOS 5.1.1 and the steps that are recommended to turn this on do not exist on my device. I am not getting any notifications of my son's requests, either to my Apple ID email address or my ICLOUD address, so I assume that these requests do not go to a mailbox then?

Thanks.
