I jumped in your account and can see that your campaigns that were sent on 7/3/15 is displaying the response data on the Overview tab. It looks like there was a delay over the weekend but looking that it has been resolved. We are digging in on this I will be sure to update you here once I have some more information.
I just wanted to follow up here. We did experience a backup of some jobs on our system last weekend which resulted in the Response page overview tab not updating with response data. Our Systems team quickly dug in and were able to push through the delayed jobs. I just wanted to provide you with some explanation for why the Response Overview tab was not updating at that time.
Feel free to reach out with any questions or if there is anything else I can do to help.
