Funniest thing about the Discover app is that there's a gap between charges/payments being processed and actually appearing in the app. A charge will show up as pending for a few days, and then there will be like a whole ass business day where it disappears, but your balance now includes it. And then the day after, it will show up as a posted charge. Same goes for payments. I have no clue why this is. No other credit card app works this way.
