So I'm not sure there's another thread like this existed yet, I've done the searching but didn't find the solid answer.

I currently have received some gifts from my neighbors, the problem is I can only click the Accept button and it says "the gift is now in your inventory" but why can't I see them? And I can't even click the Use button. I'm sure that I haven't reached the daily limit of gifting nor receiving gifts at all, if the limit of gifting is 3 neighbors per day and receiving gifts is up to 20 gifts. The only time I could use a gift from one of my neighbors, which is a glimmer dust, is so randomly, as far as I remember.

Till now I keep receiving gifts but can't use any of them. Any advices? Has anyone have the same problem as mine?
