I thought I was the only one experiencing problems with Google Adsense. The figures on my Payment History page do not tally with the figures on my Earnings Since Last Payment report. The latter report is lower by about $10.
I searched the web and found many similar complaints on various online fora. I couldn't find a single response from Google, though.
I hope this is just a temporary reporting glitch and that we Adsense users aren't really losing any money.
