I'm seeing a couple of other YourSurvey credits for you. While many surveys do credit quickly, others can take a few hours or longer. For example, in some cases the client will wait until the end of the study and then submit all credits for the entire project. If the survey doesn't redirect to the normal end page that will mean the survey won't credit immediately. Depending on how long the study runs it may take a few weeks for some users to receive credit for some surveys.
