Does anyone know how we can escalate this with Apple? I've used the Contact Us for support but there is no response. I ran into the same issue back in April. Then in May the app got accepted. No code change whatsoever with the UPD connection. Now, the submission team is rejecting the app again on the latest updates. I suspect Apple staffs are working from home and behind corporate VPN that is blocking UDP connection. TCP connection to the same server works just fine from the Apple tester's device.
