For those one who search for the solution:
1. Sony won't help you. I talked with support, gave my phone for 2 weeks for service and nothing was repaired. New xperia with facebook app is broken and unable to be fixed without a new patch.
SOLUTION:
Use app from Google Store, for example UberSync for Facebook. Work just fine.
Xperia with Facebook is in the process of being phased out and some functionality have already been removed. Therefore the exact functionality is dependent on which device and software you have.
Does anyone have any updates on this. Just got a Z3 and my Facebook contacts appear to be synced but no photos at all!
