[2020] Can’t figure out how to join/invite friends

Hello all, I am a Xbox player who just got the game through game pass and just completed the tutorial. I have 3 other friends who have also just completed the tutorial. From here, we are all trying to figure out how to invite each other or join each others game.

We have an option to press Y and invite friends to a lobby. But when this happens, nothing pops up or happens. When we create a server, we are unable to find each other on the server list.

Is there anything you have to do after you complete the tutorial to play with friends? We’ve started a mission on the table and still can’t invite after selecting both public and friends only. I know I might not be the best at describing the situation, but I can’t do much better as I’m new here

Thank you for the help
