EDIT: Just so you all know, I logged out to desktop as did my wife. We gave it like 5 minutes instead of logging back in quickly. The join button started working and we both were able to get into the instance after that.
Which world you are playing on (or are in overflow from)? The Tarnished Coast Server (overflow and tried regular world server)
What map you are on? Queensdale
How many people in your party? 2 (Xavier Greystone, level 11 guardian and Cora Driscol, level 11 warrior)
Any other details you can provide? Pretty cut and dry. Neither of us can Join each other (clicking just didn’t do anything). Also, exit to desktop and logging back into the game didn’t fix the issue.
