Yea, I think that's normal and I wouldn't be concerned about it yet. Sometimes shops get confirmed and rated right away and sometimes it takes a few days, especially over weekends. I did 5 shops for them on Friday and only 3 have been rated so far. I'm sure the other two will be taken care of at the beginning of the week.
I did have my first pay issue with CORI last week. A shop that was due to be paid didn't go through their system for some reason. I have always received proper payment through direct deposit like clockwork with them until this one. They did respond to me email, though, and said they were looking into the problem and should have an answer for me by Monday.
