I'm having a problem with this too. I've already had a bill this month, and it was for (about) $4600. I looked at the DL AMEX spend report and it said $3-4K.
I looked back to see if I had a lot of spending in the last 7-8 days of 2013 but no, it was just over $100.
So if this is supposed to be real-time, it's way low. And even if it's not, them why isn't it a least as high as my bill, minus the hundred bucks or so.
