@eskimo Hi, I see that nw_content_context_t has three optional values, NW_CONNECTION_DEFAULT_MESSAGE_CONTEXT, NW_CONNECTION_FINAL_MESSAGE_CONTEXT, NW_CONNECTION_DEFAULT_STREAM_CONTEXT, but what's the difference between message and stream? On iOS14, NW_CONTENT_CONTEXT_T is set to NW_CONNECTION_DEFAULT_STREAM_CONTEXT and is_COMPLETE is set to TRUE when using the NW_CONNECTION_SEND method. It will be treated as the last message, but in iOS12 there is no problem. Why?

@eskimo The ipv4 host we are currently connected to, want to confirm, if the ipv6 host is forcibly used for connection, is there any hope to reduce the occurrence of this crash?
