I'm facing an issue with UDP Connection in my watchOS app for duplex audio streaming using NWConnection. I’ve added the required capabilities, including background mode for audio. The connection works on the simulator (since it uses macOS networking with low-level access enabled), but on a real Apple Watch, it stays in "waiting" and fails with Error 50. Does watchOS impose extra UDP restrictions? Are additional entitlements needed?
