Yup, same here.
I am experiencing the same with my TestFlight build, was there any solution to this?
Do you have Multicast Networking Entitlement added to your app?
Can be requested via https://developer.apple.com/contact/request/networking-multicast
Is there any change to this with watchOS 8?
iOS (16/17) and macCatalyst, same behaviour in each case.
Same issue on latest iOS 17 beta. Submitted FB12773661.

#if !targetEnvironment(macCatalyst)

#endif
