We recently updated the SDK to v3.14.By default, were requesting the users for the following permissions: @"user_birthday",@"user_friends",@"public_profile",@"email",@"friends_birthday" and use the query @"https://graph.facebook.com/me/friends?fields=id,birthday,name,picture&access_token=.."
We've noticed that birthday information is missing for some of users. The behavior is inconsistent.
For example:for one of our users, only 30 out 600 friends are returned in the JSON request.. I believe it not reasonable all the others revoked their permissions.. In another case, all friends were returned, but most returned without the birthday field - see two entries from the same response:
no birthday: {"id":"616933360","name":"XXX XXXX","picture":{"data":{"url":"https://fbcdn-profile-a.akamaihd.net/hprofile-ak-ash3/t1.0-1/c40.0.100.100/s50x50/1098171_10151793243593361_626621565_a.jpg","is_silhouette":false}}}
with birthday: {"id":"590531323","birthday":"05/31/1983","name":"XXX XXX","picture":{"data":{"url":"https://fbcdn-profile-a.akamaihd.net/hprofile-ak-ash3/t1.0-1/c0.8.50.50/p50x50/1660299_10151840501221324_512792944_t.jpg","is_silhouette":false}}}
I've tried the Graph Api Explorer tool and saw similar results. The token debugger also shows that the token is valid.
Does anyone else experience this behavior? Is this a bug in facebook API?
