iOS app rejected due to Missing In-App Purchase...how long until acceptance?

Recently we submitted an app to 开发者_运维问答the App Store that utilizes In-App Purchase. We have a few different purchases available, one of which was not submitted during the initial submission process. The app was rejected for this reason:

We've completed the review of your app, but cannot post this version to the App Store because it did not comply with the App Store Review Guidelines, as detailed below:

Missing In App Purchase

We then submitted the missing In-App Purchase. Has anyone had experience with the length of time for acceptance once this step is taken? Does it take the usual 7 - 10 days that Apple estimates?

There's really no way to know. In my experience Apple's review process timing is erratic and impossible to predict. I've had reviews take anywhere from 1 hour to 2 weeks.
