Hi I'm playing on europe and never had any problems. Since yesterday I can't join groups via recruiting chat or invite people to trade with them. Either it says "Player seems to be offline" or if I can send them a invite I promptly get the message "player failed to join" mostly followed by "Player seems to be offline" if I try it to send more invites. Matchmaking in general seems to be fine since I can host matches if I start a mission and my matchmaking is set to public. I can also join any other squads if I use my starchart (for example Sorties).
