My experience shows that many publishers dont always(every month) get PIP They simply get PAYMENT ISSUED. Its True!
No PIP USA Midwest AND for the 3rd month in a row (never happened for the previous two years) Adwords is deducting from my account before Adsense hits my account. I guess this is to add insult to injury for 50% drop in Adsense earnings.
I wouldn't be surprised if we don't see payments till next week the way Google has been acting up the last few days.
