Family information is not available
Under settings>Apple Id I can see all Family Sharing info and the list of trusted devices with ONLY WIFI. When I disable WIFI on cellular data I get the error "Family Information is not available" and Trusted Device List not available.
Under Settings I have checked:
iTunes & App Store Use Cellular Data is ENABLED
Cellular , App Store & iTunes Store Cellular Data is ENABLED.
I am obviously missing something to enable cellular data to view Family Sharing. Any ideas?
