Why doesn't anger birds games (XBOX 🎮 LIVE) sync game data after hard reset?

[DBZo07]

I did hard reset on windows phone 8. But my angry bird game dint sync data.
Will data be synced if I do hard reset on Windows phone 8.1?

Nope. Developers will have to update their apps for any backup (or data roaming between devices too) to occur.
