SSDP M-Search not working in iOS 16 onwards

We are using the linux upnp for network device detection, till iOS 15.7 it working, suddenly on iOS 16 onwards the M-search request is not broadcasting.

For this there are no errors observed from the log. When we check the TCP dump, M-Search request is not observed.

In apple developer forum, suggested to enable the "Multicast" in bundle identifier, but I couldn't able to find that option while registering or updating the bundle identifier capabilities.

Can you please let us how to enable the "Multicast" option.

While is this issue will resolve if we use the Network.Framework to discover the network devices ?

This is almost certainly a local network privacy issue. See FAQ-3 in the Local Network Privacy FAQ.
