Diamond Problem

Since last week, there is something wrong with earning diamonds. When i open the game, it gives three free diamonds as usual and then i watch the cinema pass three times, so it should give at least 9 diamonds per day, right? I had 56 diamonds on Friday. Since then, i still have 56 diamonds. At first, i can see diamonds after i earned with doing all this cinema pass stuff but when i close the app and open it again, it shows that i still have 56. Why is that happening? Will you fix that?
