Last week I had made 5 sales with one return according to their analytics. This morning, I log-in and the analytics have changed. There are only 2 sales reported with NO returns. I'm assuming there were more returns...but why isn't it reflected in the stats? I find it worrisome that Clickbank just changes their analytics like that. Had I not been checking in, I wouldn't have even known there were those original sales. Is this normally how they do things? Just erase? Seems to me it's risky to go out of your way promoting these products if Clickbank doesn't take responsiblity for accurate reporting of sales and returns...
Have you checked further back then 14 days of your analytics? It could be possible that they were done on the 15th day, meaning they wouldnt show up anymore
