Is your app “Waiting for Review” or “In Review”? If it’s “Waiting for Review”, then it has nothing to do with your content or using UDID’s by the ad vendors. It simply means you’re in the queue to be reviewed and it’s not been picked up by a reviewer yet.
Once it changed to “In Review” and you go 8 days, then there might be problems.
From my experience these are the times for the review process:
Waiting for Review -> In Review: 7-8 days.
In Review -> Processing for App Store: New Apps 6-24 hours, existing apps, around 30 minutes lately.
Processing for App Store -> Ready for Sale: under 10 minutes.
Ready for Sale -> (until you can find it, no email for that state): 2-6 hours for new apps. Obviously for existing apps, you’re still in the search data.
For empirical evidence… I uploaded both Omniblaster and Omniblaster Lite on Sunday March 18 and they both went into review today, right about 8 days to the hour. There are a lot of uploads right now with people producing 5.1/new iPad versions. My other two apps that I updated on a Friday night went into review on Saturday, again 8 days.
Interestingly enough, I discovered a debug alert I left on in Omniblaster and rejected the binary a couple of days ago and resubmitted it, and it went into review a couple of hours ago, so I did not appear to loose my place in line with it. [import]uid: 19626 topic_id: 23907 reply_id: 96370[/import]
