Are you talking about the Hubpages ad program and earnings from the previous day? If so, the Hubpages ad program is still fairly new and I am sure there are bugs that need to be worked out along the way. My stats always come up the same day or the next day.
As far as pending payments this shouldnt happen each day as you only get paid when you meet the threshhold and this will happen several weeks after meeting that amount. Payments are once a month.
