Hi, I am still new; but, I just encountered something similar. I was requesting shops and was getting every one I requested; then, my requests failed to get any response. I noticed they listings were still active and new ones appeared too.
I sent an email to Help-desk and actually got a phone call back. They explained: There is a limit on the number of this particular shop that can be done on a monthly basis. I had hit the number and could not have another one until the next month.
Two days later, we were into a new month and I got a call granting me my next assignment and a reminder that we were into a new month and everything is fine. Because of curiosity, I asked: Why is there a limit? True or Not, the response was two-fold: First, they were afraid targets may communicate and identify the shopper. Second, to diversify the incoming reports for more perspectives.
I thought it was worth mentioning in this post.
