If I try to invite someone to my fireteam, I get "Please enter a valid, valid battletag." And so does other people too, when they try to invite me. Been manually written and copypasting whole name for example : /invite thisuser#33442 . Any other have same problem? . My internet connection is solid, pc good spec and uptodate with drivers and have all dlc/passes. Fireteam setting been tried with everything "open, invite only etc".
