Update: My app was approved on October 25, approximately 19 days after I submitted it on October 6. I have now released the approved version. There were no replies to this thread, and I cannot say whether posting here had any effect, but I wanted to share the outcome for other developers experiencing a similar wait. I’m relieved that the review is finally complete. However, I still hope Apple improves communication during extended review delays, especially when support inquiries go unanswered. Even a brief status update would make the waiting process much less frustrating.
