It seems to work about 10% of the time for me. Also it activates every keybind you may have while its open. So for instance if I go to scroll up and read older comments, it will zoom my camera in at the same time. Or if I start typing, it will start opening menus and activating skills.
It was working and active when I first logged in but I now haven’t seen any comments since the first few minutes I logged in.
