Did this ever get fixed? If so, how long did it take and what was the issue? was this testflight submission or official app store review? I am going through this process now so trying to find some insight.

Took mine about 4 business days. Got approved 3 days ago. I did not get a notification email either, just logged on one morning and boom approved. I think their typical timeline is 48 hours but one of their customer service reps told me they are experiencing unusually high volumes of service and review requests.
