Myself and all of my friends have good internet and open NAT's. It seems like more and more we are trying to join each other's party chat and we'll get, "Due to network limitations, party chat is unavailable." Not just my friends, but I've seen people with this all over the forums on many websites. I'm sure Microsoft is working hard, but please fix this. Connecting with friends should have been and still should be a number one priority overall.
I've done hard resets, resetting modem/router, etc. If there is an actual fix to this, please feel free to post everyone can see. Thanks!
