I did contact support.
Even they are showing more signups for me than are being shown in transactions. They told me that it "takes awhile" for the page to update (I'm still waiting for it..been 1/2 hour now and no change).
How long SHOULD it take from signup to being posted in transactions?
Btw..to all affiliates..I was told that yes, stats are messed up and will stay that way awhile even after maintenance is done.
