Followup for my previous bug report in message #4. It looks like heart display in friend list is Buggy McBuggyFace.
I have game installed on several devices (two phones, tablet and Bluestacks), and I play the game on each. These two screenshots were taken on phone and Bluestacks within 10 seconds of each other.
Notice how one shot shows that I received (and collected) heart from DON THREAD ON ME and another shows that I haven't done either. And why is my "Recent" showing as 3/30 on one device and 1/30 on another?
Only way that should happen is if data is stored on client side and is not properly synced to server side (and to other clients). There must be some syncing, else other people's hearts would show on one client only which is not happening for most people. But it is happening for some.
Also, please note that this is not due to temporary lack of sync for currently logged in people. I have other people showing same pattern. One of them was logged in 1 hour ago, one 4 hours. Plenty of time to sync.
