Hi everyone ! Since some hotfix (i have only noticed it after the 21.0.6), i'm now unable to invite or being invited in dojo to trade with someone. I'm of course in Public mode.  When I'm sending an invitation, it says "XXXX Failed to join". And if someone send me and invitation, i just receive nothing and i'm appearing as offline. But I have no problem at all to join public missions with random players as described in this topic below....
