Update (28 October): Our submission was reviewed on 20 October, and the only issue raised was a small screenshot detail under Guideline 2.3.10. A drawn status bar in a few of our screenshots looked non-iOS. We removed it and resubmitted within an hour, in the same submission, which stays in the expedited queue.
That fix has now been in “Waiting for Review” for 8 days, and it’s been 29 days since our first submission on 29 September. The app binary hasn’t needed a single change since then.
Could someone from App Review please take a look and help us go live quickly?
