This situation tracks. My app submission has been in "Waiting for Review" since January 27. I contacted App Review Support after 5 days, but never heard back. Additionally, I went a step further and scheduled an App Review appointment with the team, but they declined the request with no explanation.

This seems to be a widespread issue. My app has been in "Waiting for Review" since Jan 27 (technically, I submitted the app on Jan 23, but I thought "resubmitting" it after no movement for 4 days would nudge it, but in hindsight, that likely made it worse), and I've submitted two requests to Apple support with no response.
