Those usually credit within one hour. Sometimes there is a delay of another hour. It should have credited by now. As a rule they seem to be crediting fine so there must have been something that kept that one from crediting. I did one this morning and got credit. Also, I notice that the stoplight on that one is green so they are crediting for the majority of people who are taking them. Did you clear cookies between taking one on Monday and one on Tuesday? Did you take a greenfield and a ytc without clearing cookies in between?
