Dear Sir / Madam,
I've uploaded an update for an app a day before, still 20 hours not status updated yet, as we have a crucial launch.
Waiting for review
You can ask the App Store Review team for an expedited review, but I really wouldn't post an update for a "crucial launch" and expect it to be reviewed and approved within a day - at the weekend.
Plan better in future.
Desperate times, desperate measures, tried everything bro
