I had a similar thing happen- I use my card for business and the accounting department delayed paying less than 1% of my bill, due about 10 days ago, by 2 days. I got a quick call from AmEx even before the bill was due as the balance was very high, even though I have it fully paid each month.

Now my MR points haven't posted- I'd never bothered to see when they post, but how many days after a bill is paid in full do the MR points post?

Thanks.
