Our iOS app (1.0.0) was rejected Oct 21 under 2.3.4 (app preview framing) and 2.5.4 (audio/VoIP background modes). We replaced the previews, replied with a real-device recording of the voice feature, and resubmitted Oct 22. It's been Waiting for Review since, with no reply in App Store Connect. We've also contacted Developer Support.
Is there anything else we should do, or is a longer wait normal after a 2.5.4 resubmission? Thanks.
