Please help me invite someone to my game

How do I invite a friend to my game (ps4) I’m at a safe house and I have my multi-player up and I hit square to invite and it does nothing my friend has the same issue please help!!!

When you open multiplayer menu wait a few seconds before you press invite button. Sometimes it can take up to 10-15 seconds after you hit the button until invite menu pops up. So wait before you try again.
