@robertomuj - no, I didnt edit app profile. Probably a coincidence, but I did do a test flight version update (in my other developer account, however). This was maybe an hour prior - and that test flight app update was immediately approved. Then the other app that was stuck on "waiting for review" also suddenly got approved. That seemed odd, but probably unrelated, I guess. Good luck.

Not sure if Apple saw this thread or my support requests, or if we just finally got through the queue - but the app was just approved. Just FYI (if it helps anyone else going through a similar situation), we didnt received any responses to the support request emails over the last 12 days. Also, I have been keeping an eye on the dashboard - it went straight from "waiting for review" to approved, no "in review" status (that I was aware of at least, I checked it probably 1hr prior to receiving the approval email). Anyway, glad it's finally sorted, a lot of stress alleviated. Good luck to the others in the forum, I hope they clear for you soon too.

Hello Apple App Review Team, I'm following up as this submission has now remained in "Waiting for Review" for 11 days. Despite an expedited-review request and three separate Developer Support enquiries, we have received no response. With just 18 days remaining until the 7 November performance, the delay is becoming increasingly critical to the preparation of approximately 2,000 participants. Could someone from the App Review team please investigate whether our submission is progressing normally and assist with an urgent escalation? Any assistance or acknowledgement would be greatly appreciated.
