Sugar drops not synced between desktop and mobile apps?

I have been playing this on desktop and my mobile phone. Sometimes the sugar drops I collected on mobile app is not shown in the desktop facebook app. For example I just collected 23 sugar drops on my phone, and then I turned to the desktop facebook app but saw only 0 sugar drops.
