IIm curious on how to become scout shopper certified. I followed the link no luck though

I took the certification test end of may begin of June. I've been trying to schdule shops but it says Im not a shopping scout even though I have my log in info and everything. Other thing is why are only people who have been doing it for a long time get to do the shops on a weekly basis? How does anyone get the chance to even try 1?And the same people getting same location week by week isn't a lil sus? What's legacy because I've been signed up as a shopper for 4 or more years just don't get the chance to try and if I do get one it's so little that it doesn't cover a gallon of gas in my car.
