Our group has been trying to utilize matchmaking and have had nothing but issues. If I play multiplayer solo I have no issues. However when we try find a game we sit in the lobby indefinitely while it “searches” for more players.
In some cases my friends and I can connect to the same lobby but some can see each other and others cannot however some of the people in the lobby can see everybody.
Not sure if others are experiencing this same problem, if so, please post here.
Note: my XB1 is in a DMZ and I have all ports necessary for Xbox Live forwarded as well. Have not had this issue with other games.
