Thanks, I’ll freeze resubmissions and audit deterministic runtime behavior first.

Thanks for the feedback. You’re right — my original post was too broad and didn’t describe the app clearly enough. I’ve narrowed it down to the actual technical context: it is a custom-built iOS VPN app using Network Extension / Packet Tunnel, with no purchased or reused template source. I’ll simplify the post and focus on the specific 4.3(a) → 5.6 progression and the technical causes that might explain it.
