I have two waiting-for-review updates that have been sitting in the queue for 9 days now. This seems much longer than my past experience of 2-4 days turn-around. I wonder if these delays are related to the corrupt updates issue.
Yes, absolutely. In fact, based on the fact that my apps frequently sit in 'In Review' (versus 'Waiting for Review') for 12+ hours usually, it wouldn't shock me if they had multiple people review each submission.
How much they play around with the app seems to vary - I've had odd, hard-to-trigger bugs get my app rejected, even though they existed for several prior versions.
Each app submission/update costs Apple a fair amount of money to review.
It definitely seems like multiple people can be involved if there is uncertainty on whether to reject the app. From experience, I've found that if my app is sitting in "In Review" status for more than a certain number of hours, it's likely to get rejected.
The only time Apple gave out hard numbers on their review setup, a couple of years ago, they had two reviewers check each submission, with an average of 6.5 minutes per reviewer per submission spent checking it. Obviously, that average contains quite a bit of variation.
Interesting. I don't think I've ever had one take < 1 hour, and most are 3+ hours from 'In Review' to 'Processing for App Store' or 'Rejected'. 12-24 hours is fairly common for me, and I just had one approved the other day that was 'In Review' for ~48 hours.
We had a app finally get thought the review queue last week after a 12 day wait. Maybe there's a recent surge of apps hitting the store post-WWDC? No problems with corrupted binaries for us though.
Wow 12 days. Haven't had to wait that long for a few years now. Probably also a slew of updates due to developers updating keywords caused by the recent change to the App Store search algorithms.
