I did a search but came up with no solid discussion about this.
There are features for contacts (birthday for example) on contacts online that you can edit but not on the phone.
I see notifications in calendar for contact anniversaries and events but no place to add them in the contacts section.
If I add a birthdate to someone in contacts, shouldn't that automatically appear in the calendar?
On the phone, there is a separate area for address, city, state and zip but online it's all one field.
Also on the phone you have a spot for given name and family name but this field does not appear in the online contacts.
Considering this is supposed to be a "Google experience phone" I see a lot of mismatching between features. Maybe I am missing something and if so, please point me in the right direction.
