Oh, I thought you were referring to the balance clearing.
My commissions went into January's Publisher payments earlier today. CJ may well do this at different times for different accounts, so the whole process may be spread over a number of days.
If you get to the 21st and it's still not in publisher payments, it may mean that CJ are investigating your commissions. I have never had commissions go into PP later than the 21st of the month.
Hope you dont have a problem.
