This has been going on for weeks, for me anyway, but I'm just now reporting it. The gifting system has a lot of lag. That is to say, some gifts don't show up until hours after they've been sent.

I can have my news feed up, and, let's say I visit a neighbor, and then pull up my news feed again. A gift will show up that wasn't there before, but its time stamp is from hours earlier. Sometimes force closing the app is a way to get delayed gifts to instantly show up in my feed.

I've re-installed the game several times for other reasons so I don't think that's going to solve this issue.
