I've been using Adsense for a few months and had no problems up to now. I logged in today to check if my March earning's had been finalised and they had. However, the problem is my "Payment History" suggests during March I only earned just over £4000 (not sure if I'm allowed to disclose exact amount), when according to my reports, "last month - March" I made almost £7000. This is a lot of money to me and I can't understand why it's not listed on "Payment History". I know the reports display "estimated earnings" but surely it can't be that different? . Moreover, I understand that the variation of the exchange rate could slightly adjust the earnings, but again not that much surely? Is this a bug google's end and something they will sort out, or will I miss out on this huge chunk of my earnings when I get payed at the end of the month? Has anyone been in a situation similar to this before.
