Family Sharing when Apple ID is not an @icloud.com
Hello,
I use @me.com (iCloud.com) to connect to iCloud services. However, my Apple ID is @gmail.com and all my purcases are made using this (@gmail.com) Apple ID.
How do I share purchases with my family members if Apple organizes it is via iCloud? To make it Apple way I need to sign in to iCloud with my (@gmail.com) Apple ID which prevents me from using all iCloud.com services or start using @icloud.com as my Apple ID for puchases. However, as far as I can understand there is no way of moving all the purchases from one Apple ID (i.e.@google.com) to another - @icloud.com.
Is there any way me use Family Sharing feature introduced in iOS 8 and still keep status quo - icloud.com/me.com for iCloud and @gmail.com as Apple ID for iTunes and Mac App Store purchases?
