As the title states any invites between us never show up. Seems to be about 90% of the time we try and play the past at least 3-4 months? Most of the time we give up and go play something else because it ends up being a waste of our time trying to get it working. The only time we have gotten it working is through odd combo's of restarting the game/PC/ubi client, but again it's taken so long each time we've gotten it to work that it's not even worth our time anymore. Any time that we've gotten it working is not consistent in the resolution and there are no error messages. So I am unable to show any steps to reliably fix it. The invites simply do not show up to the friend being invited. Every other game that I play that has any type of co-op and/or multiplayer works flawlessly with no issues. This is the only game that does not. Both of us are wired directly to our routers and are not using VPNs.
