For the last few days I haven't been able to see any earnings or impressions for Amazon CPM ads. To be exact this seems to be issue since March 24th, and to this day (the 27th) the problem still persist- zero page views and zero $. Apparently they know about this issue, but guess the guys who can fix it are all on vacation or something, which isn't a big confidence booster for the program for reporting to be down for so long.
