Is this jst another Bug?Or do u hav this problem2?

Just wondering if I’m the only one having this problem where I invite my friend*s to play co-op and they then accept it yet they never join my session/party. It would still say 1/16 in current session, and a lot of the times I don’t even see any of my friends listed online on the roster on Halo:MCC even though on my friends list/xbox chat party it says they are. Sometimes it will even say in the xbox live chat party that I’m in their game or they are in mine (which they aren’t).

When they host the game and send me an invite I say “xbox launch” and NOTHING happens (yet the xbox did in fact hear me and trys to launch)… -.-
