My app has been stuck on 'Waiting for review' for over 4 days. Unlike before, I will get feedback within 48 hours, but now I have been 4 days in and no one seems to have checked the app at all. Any advice?

Our application, Yunlen, was unexpectedly rejected after a minor UI update, despite having been live on the App Store for nearly a year. The rejection cites "Crypto related content," an issue we have repeatedly clarified with the Apple Review Team; frustratingly, we have been forced to provide the same detailed explanation three separate times in the same review thread, indicating our responses are being ignored and resulting in a protracted and frustrating 10-day delay to a simple update.
