It has PIP at the bottom in the adsense account but at the top it says issued on the 23rd. Normally its in the account 2/3 days after issue date, but its now January 3rd and payment still isn't in my account. I know its been the holiday period with Christmas Day, Boxing Day, New Years Day and Bank Holiday yesterday, all of which were non business days so the banks were closed, but there were several days in between which were usual business days (27th till the 30th of December), enough time for payment to have received by the bank.
I have always had payments received before the end of the month, usually by the 27th or the 28th.
